Psychological aggression is the most prevalent form of aggression in dating relationships, with women perpetrating as much, if not more, psychological aggression than men. Researchers have advocated for an examination of the consequences that follow psychological aggression for the perpetrator, in hopes that this will lead to innovative intervention programs aimed at ameliorating dating violence. The current study investigated the self-reported consequences of having perpetrated psychological aggression against a dating partner among female college students in a current dating relationship (N = 115). Participants endorsed numerous consequences as having followed their perpetration of psychological aggression, including both punishing and potentially reinforcing consequences. Furthermore, findings indicated that for some perpetrators, psychological aggression may function as a method of emotion regulation. Implications of these findings for future research and intervention are discussed. PMID:22550148

This study examined the effects of two school-based programs on the perpetration of nonphysical aggression, physical violence, and intimate partner violence among high-risk secondary school students in an economically disadvantaged and predominantly Latino school district. The intervention program was El Joven Noble, and the control program was the Teen Medical Academy. The study used a repeated-measures quasi-experimental intervention/control design. The participants self-reported the previous 30 days' acts of nonphysical aggression, physical violence, and intimate partner violence at baseline and at 3 and 9 months after enrollment. Program- and grade-level effects at 3 and 9 months were examined using three-factor analyses of covariance models with one factor for repeated measures. The covariate in each of the models was the baseline measure of the dependent outcomes. No significant baseline differences were found between the participants in the intervention (n = 96) and control (n = 127) programs. At 9 months after enrollment in the study, high school students who participated in the Teen Medical Academy reported fewer acts of nonphysical aggression (p < .001) and physical violence (p = .002) than high school students who participated in El Joven Noble. Students who participated in the Teen Medical Academy also reported fewer acts of intimate partner violence (p = .02) than students who participated in El Joven Noble. High school students who participated in a health career promotion program reported fewer acts of aggression and violence as compared with high school students who participated in a culturally tailored character development program.

Relationship between boys' normative beliefs about aggression and their physical, verbal, and indirect aggressive behaviors.

PubMed

Lim, Si Huan; Ang, Rebecca P

2009-01-01

This study examined the contribution of general normative beliefs about aggression and specific normative beliefs about retaliatory aggression in predicting physical, verbal, and indirect aggressive behaviors. Two hundred and forty-nine Grade 4 and Grade 5 boys completed the Normative Beliefs about Aggression Scale (NOBAGS) and provided self-reports on the frequency of their physical, verbal, and indirect aggressive behaviors. A series of hierarchical multiple regression analyses revealed that general normative beliefs about aggression contributed significantly in predicting all three types of aggressive behaviors. When general normative beliefs about aggression were controlled for, specific normative beliefs about retaliatory aggression against males but not specific normative beliefs about retaliatory aggression against females, contributed significantly to predict physical, verbal, and indirect aggressive behaviors. Implications for intervention programs are discussed.

Research suggests that early classroom experiences influence the socialization of aggression. Tracking changes in the aggressive behavior of 4,179 children from kindergarten to second-grade (ages 5-8), this study examined the impact of 2 important features of the classroom context--aggregate peer aggression and climates characterized by supportive teacher-student interactions. The aggregate aggression scores of children assigned to first-grade classrooms predicted the level of classroom aggression (assessed by teacher ratings) and quality of classroom climate (assessed by observers) that emerged by the end of Grade 1. Hierarchical linear model analyses revealed that first-grade classroom aggression and quality of classroom climate made independent contributions to changes in student aggression, as students moved from kindergarten to second grade.

2014-01-01

While much prior research has documented the negative associations between aggression, peer relationships, and social skills, other research has begun to examine whether forms of aggression also may be associated with prosocial skills and increased social status. However, few studies have examined these associations within diverse samples of elementary aged youth. The current study examined the associations between aggression, popularity, social preference, and leadership among 227 urban, ethnic minority (74 % African American, 9 % bi-racial including African American, 12 % other ethnic minorities, and 5 % European American) elementary school youth (average age 9.5 years, 48.5 % female). Results indicated that in an urban, high risk environment, displaying aggressive behaviors was associated with increased perceived popularity, decreased social preference, and, in some cases, increased perceived leadership. The results also suggested gender differences in the association between the forms of aggression (i.e. relational and overt) and popularity. The current study underscores the importance of examining youth leadership along with forms of aggression and social status among urban minority youth. Implications for future research and aggression prevention programming are highlighted. PMID:23086015

2009-03-01

Exposure to marital psychological and physical abuse has been established as a risk factor for children's socio-emotional, behavioral, and cognitive problems. Understanding the processes by which children develop symptoms of psychopathology and deficits in cognitive functioning in the context of marital aggression is imperative for developing efficient and effective treatment programs for children and families, and has far-reaching mental health implications. The present paper outlines our research program, Child Regulation and Exposure to Marital Aggression, which focuses on children's emotional and physiological reactivity and regulation as pathways in the marital aggression-child development link. Findings from our research program, which highlight the importance of children's regulatory processes for understanding children's adjustment in contexts of intimate partner violence, are presented, and future directions in this line of inquiry are outlined.

The Microgravity Research Program (MRP) participated aggressively in Phase 1 of the International Space Station Program using the Russian Mir Space Station. The Mir Station offered an otherwise unavailable opportunity to explore the advantages and challenges of long duration microgravity space research. Payloads with both National Aeronautics and Space Agency (NASA) and commercial backing were included as well as cooperative research with the Canadian Space Agency (CSA). From this experience, much was learned about long-duration on-orbit science utilization and developing new working relationships with our Russian partner to promote efficient planning, operations, and integration to solve complexities associated with a multiple partner program. This paper focuses on the microgravity research conducted onboard the Mir space station. It includes the Program preparation and planning necessary to support this type of cross increment research experience; the payloads which were flown; and summaries of significant microgravity science findings.

Kachadourian, Lorig K; Quigley, Brian M; Leonard, Kenneth E

2014-01-01

Objective: Alcohol aggression expectancies have been found to be associated with increases in aggressive behavior. However, research has not consistently examined evaluations of such behavior. This is unfortunate as both expectancies and evaluations may play a role in whether such behavior will occur. Given this, the current study cross-sectionally examined the associations between alcohol aggression expectancies, evaluations of alcohol-related aggression, indicators of excessive drinking, and alcohol-related verbal and physical aggression. Method: The sample consisted of 280 married and cohabiting couples. These couples reported on excessive drinking indicators, alcohol expectancies and evaluations, and alcohol-related verbal and physical aggression during the past year. Results: Findings showed that verbal aggression was positively associated with indicators of excessive drinking among females and with alcohol aggression expectancies for females who evaluated such aggression positively. For males, aggression expectancies and indicators of excessive drinking were positively associated with verbal aggression. For physical aggression, results showed that indicators of excessive drinking and aggression expectancies were associated with physical aggression for females. For males, aggression expectancies were positively associated and evaluations were negatively associated with physical aggression. Conclusions: These findings add to previous research on alcohol aggression expectancies in close relationships and emphasize the importance of considering evaluations of alcohol-related behavior and how they may play a role in intimate-partner violence and aggression.

This study examined the associations between maladaptive dependency-related schemas, posttraumatic stress disorder (PTSD) hyperarousal symptoms, and intimate-partner psychological and physical aggression in a sample of court-referred men (N = 174) participating in a domestic-abuser-intervention program. The men were largely African American; average age was 33.5 years. The extent to which hyperarousal symptoms moderated the association between dependency schemas and aggression was also examined. Maladaptive dependency-related schemas were positively associated with severe psychological, and mild and severe physical aggression perpetration. Hyperarousal symptoms were positively associated with mild and severe psychological aggression, and mild physical aggression perpetration. Multiple regression analyses showed a significant interaction for mild physical aggression: For those with high levels of hyperarousal symptoms, greater endorsement of maladaptive dependency schemas was associated with the perpetration of aggression (B = 0.98, p = .001). For those with low levels of hyperarousal symptoms, there was no association between dependency schemas and aggression (B = 0.04, ns). These findings suggest that focusing on problematic dependency and PTSD-hyperarousal symptoms in domestic-abuser-intervention programs may be helpful, and that examining related variables as possible moderators between dependency schemas and intimate aggression would be a fruitful area for future research.

Reductions in aggressive behavior within the context of a universal, social emotional learning program: Classroom- and student-level mechanisms.

PubMed

Portnow, Sam; Downer, Jason T; Brown, Joshua

2018-06-01

The present study uses data from 35 third through fifth-grade urban classrooms and 531 students to examine the extent to which student-level social and emotional skills (e.g., low hostile attribution bias and low aggressive interpersonal negotiation strategies) and emotionally supportive learning environments predict aggressive behavior over the course of a school year. Results of multiple regression analyses indicated that across teacher-reported measures of aggressive behavior, more classroom emotional support over the course of the school year predicted less aggressive behavior in spring, particularly for children whose hostile attribution bias decreased over the course of the year. According to a child-reported measure of aggressive behavior, declines in aggressive interpersonal negotiation strategies over the course of the year also predicted less aggressive behavior in spring. Moreover, these results operated similarly across all children. Implications for SEL programs are discussed. Published by Elsevier Ltd.

A Multi-Session Attribution Modification Program for Children with Aggressive Behaviour: Changes in Attributions, Emotional Reaction Estimates, and Self-Reported Aggression.

Vassilopoulos, Stephanos P; Brouzos, Andreas; Andreou, Eleni

2015-09-01

Research suggests that aggressive children are prone to over-attribute hostile intentions to peers. The current study investigated whether this attributional style can be altered using a Cognitive Bias Modification of Interpretations (CBM-I) procedure. A sample of 10-12-year-olds selected for displaying aggressive behaviours was trained over three sessions to endorse benign rather than hostile attributions in response to ambiguous social scenarios. Compared to a test-retest control group (n = 18), children receiving CBM-I (n = 16) were less likely to endorse hostile attributions and more likely to endorse benign attributions in response to a new set of ambiguous social situations. Furthermore, aggressive behaviour scores reduced more in the trained group than in the untrained controls. Children who received attribution training also reported less perceived anger and showed a trend to report more self-control than those in the control group. Implications of these findings are discussed.

The research goals were to use the constructs of harm and intent to quantify the severity of aggression in the real-world setting of the bar/club, to describe the range of aggressive behaviors and their relationship to harm and intent, and to examine gender differences in the form and severity of aggression. Systematic observations were conducted by trained observers on 1,334 nights in 118 bars/clubs. Observers documented a range of aggressive acts by 1,754 patrons in 1,052 incidents, with many forms of aggression occurring at more than one harm and intent level. Women used different forms of aggression, inflicted less harm, and were more likely to have defensive intent compared with men. Implications of the findings for research and measurement of aggression and applications to preventing aggression and violence are discussed.

The genetics of aggression: Where are we now?

PubMed

Asherson, Philip; Cormand, Bru

2016-07-01

Aggression, an overt behaviour with the intention to inflict damage, is a physiological trait with important roles throughout evolution, both in defence and predation. However, when expressed in humans in the wrong context, aggression leads to social maladjustment and crime. This special issue is about the genetic and neurobiological basis for aggression. Most of the 12 works presented here have been prepared by members of five international consortia established under the auspice of the FP7 and H2020 programs of the European Union to investigate different aspects of aggression and related behavioural phenotypes, including delineation of subtypes, aetiological mechanisms, neurobiology, neuroimaging, biomarkers, animal models and development and assessment of new treatments. Research on human aggression has largely focused on the societal causes of violent behaviour with relatively little focus on the underlying neuroscientific basis. However, interesting findings are emerging which suggest that by identifying distinct pathways to aggression, better targeting of social, psychological and medical treatments, can lead to improved outcomes for individuals and society. This issue represents a state of the art review of current neurobiological understanding of human aggression and a starting point for concerted efforts to move the field towards the development of new strategies for prevention and treatment. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The Influence of Treatment Attendance on Subsequent Aggression among Severely Mentally Ill Substance Abusers

2014-01-01

The interrelationships between severe mental illness, substance use, and aggression are of longstanding importance with implications for community treatment programs, treatment research and public policy. Through the analysis of longitudinal data collected from 278 patients over a 6-month period following admission to an outpatient dual diagnosis treatment program, this study examined the association between dual diagnosis treatment attendance and subsequent aggression among individuals diagnosed with both a severe mental illness and a substance use disorder. We also tested substance use and psychiatric symptoms as mediators of this treatment-aggression relationship. The results of structural equation modeling analyses indicated that dual diagnosis treatment was associated with lower levels of subsequent aggression. Mediational analyses indicated that greater treatment involvement was associated with reduced substance use, which was associated with lower levels of aggression; thus, substance use was found to mediate the relationship between dual diagnosis treatment and aggression. Surprisingly, severity of psychiatric symptoms did not predict later aggression. These findings suggest that targeting substance use reduction in treatment may have the additional benefit of reducing the risk of later aggression among dual diagnosis patients. PMID:25124261

The object of my aggression: Sexual objectification increases physical aggression toward women.

Vasquez, Eduardo A; Ball, Louisa; Loughnan, Steve; Pina, Afroditi

2018-01-01

Objectification involves reducing someone to a sexual object, rather than seeing them as a full person. Despite numerous theoretical claims that people are more aggressive toward the objectified, and empirical evidence that objectification is linked to high willingness to aggress, rape proclivity, and aggressive attitudes, no research has examined a causal link between objectification and physical aggression, particularly in the context of provocation. In two experiments, we examined this predicted link. In Experiment 1, using a 2 (objectification: no/yes) × 2 (provocation: no/yes) factorial between-subjects design, we investigated the effects of objectification, induced via body focus during a face-to-face interaction, and provocation on physical aggression toward a female confederate. Our results revealed a significant main effect of provocation, a marginal main effect of objectification, and a significant interaction between these variables. In the absence of a provocation, focusing on a woman's body increased aggression toward her. Experiment 2 replicated Experiment 1 using a video of a target woman instead of a face-to-face interaction. Again, our results showed a significant two-way interaction between objectification and provocation, wherein objectification increased aggression in the absence of provocation. Overall, this research indicates that objectification can lead to heightened physical aggression toward objectified women. © 2017 Wiley Periodicals, Inc.

Adolescents’ Aggression to Parents: Longitudinal Links with Parents’ Physical Aggression

Margolin, Gayla; Baucom, Brian R.

2014-01-01

Purpose To investigate whether parents’ previous physical aggression (PPA) exhibited during early adolescence is associated with adolescents’ subsequent parent-directed aggression even beyond parents’ concurrent physical aggression (CPA); to investigate whether adolescents’ emotion dysregulation and attitudes condoning child-to-parent aggression moderate associations. Methods Adolescents (N = 93) and their parents participated in a prospective, longitudinal study. Adolescents and parents reported at waves 1–3 on four types of parents’ PPA (mother-to-adolescent, father-to-adolescent, mother-to-father, father-to-mother). Wave 3 assessments also included adolescents’ emotion dysregulation, attitudes condoning aggression, and externalizing behaviors. At waves 4 and 5, adolescents and parents reported on adolescents’ parent-directed physical aggression, property damage, and verbal aggression, and on parents’ CPA Results Parents’ PPA emerged as a significant indicator of adolescents’ parent-directed physical aggression (odds ratio [OR]: 1.25, 95% confidence interval [CI]: 1.0–1.55; p = .047), property damage (OR: 1.29, 95% CI: 1.1–1.5, p = .002), and verbal aggression (OR: 1.35, 95% CI: 1.15–1.6, p < .001) even controlling for adolescents’ sex, externalizing behaviors, and family income. When controlling for parents’ CPA, previous mother-to-adolescent aggression still predicted adolescents’ parent-directed physical aggression (OR: 5.56, 95% CI: 1.82–17.0, p = .003), and father-to-mother aggression predicted adolescents’ parent-directed verbal aggression (OR: 1.86, 95% CI: 1.0–3.3, p = .036). Emotion dysregulation and attitudes condoning aggression did not produce direct or moderated effects. Conclusions Adolescents’ parent-directed aggression deserves greater attention in discourse about lasting, adverse effects of even minor forms of parents’ physical aggression. Future research should investigate parent-directed aggression as

Benefits and Costs of Aggressive Energy Efficiency Programs and the Impacts of Alternative Sources of Funding: Case Study of Massachusetts

Cappers, Peter; Satchwell, Andrew; Goldman, Charles

2010-08-06

Increased interest by state (and federal) policymakers and regulatory agencies in pursuing aggressive energy efficiency efforts could deliver significant utility bill savings for customers while having long-term implications for ratepayers (e.g. potential rate impacts). Equity and distributional concerns associated with the authorized recovery of energy efficiency program costs may necessitate the pursuit of alternative program funding approaches. In 2008, Massachusetts passed the Green Communities Act which directed its energy efficiency (EE) program administrators to obtain all cost-effective EE resources. This goal has translated into achieving annual electric energy savings equivalent to a 2.4% reduction in retail sales from energy efficiencymore » programs in 2012. Representatives of electricity consumer groups supported the new portfolio of EE programs (and the projected bill savings) but raised concerns about the potential rate impacts associated with achieving such aggressive EE goals, leading policymakers to seek out alternative funding sources which can potentially mitigate these effects. Utility administrators have also raised concerns about under-recovery of fixed costs when aggressive energy efficiency programs are pursued and have proposed ratemaking policies (e.g. decoupling) and business models that better align the utility's financial interests with the state's energy efficiency public policy goals. Quantifying these concerns and identifying ways they can be addressed are crucial steps in gaining the support of major stakeholder groups - lessons that can apply to other states looking to significantly increase savings targets that can be achieved from their own ratepayer-funded energy efficiency programs. We use a pro-forma utility financial model to quantify the bill and rate impacts on electricity customers when very aggressive annual energy efficiency savings goals ({approx}2.4%) are achieved over the long-term and also assess the impact of

The impact of classroom aggression on the development of aggressive behavior problems in children

PubMed Central

Thomas, Duane E.; Bierman, Karen L.

2009-01-01

Prior research suggests that exposure to elementary classrooms characterized by high levels of student aggression may contribute to the development of child aggressive behavior problems. To explore this process in more detail, this study followed a longitudinal sample of 4,907 children and examined demographic factors associated with exposure to high-aggression classrooms, including school context factors (school size, student poverty levels, and rural vs. urban location) and child ethnicity (African American, European American). The developmental impact of different temporal patterns of exposure (e.g., primacy, recency, chronicity) to high-aggression classrooms was evaluated on child aggression. Analyses revealed that African American children attending large, urban schools that served socioeconomically disadvantaged students were more likely than other students to be exposed to high-aggressive classroom contexts. Hierarchical regressions demonstrated cumulative effects for temporal exposure, whereby children with multiple years of exposure showed higher levels of aggressive behavior after 3 years than children with primacy, less recent, and less chronic exposure, controlling for initial levels of aggression. Implications are discussed for developmental research and preventive interventions. PMID:16600064

Implicit cognitive aggression among young male prisoners: Association with dispositional and current aggression.

PubMed

Ireland, Jane L; Adams, Christine

2015-01-01

The current study explores associations between implicit and explicit aggression in young adult male prisoners, seeking to apply the Reflection-Impulsive Model and indicate parity with elements of the General Aggression Model and social cognition. Implicit cognitive aggressive processing is not an area that has been examined among prisoners. Two hundred and sixty two prisoners completed an implicit cognitive aggression measure (Puzzle Test) and explicit aggression measures, covering current behaviour (DIPC-R) and aggression disposition (AQ). It was predicted that dispositional aggression would be predicted by implicit cognitive aggression, and that implicit cognitive aggression would predict current engagement in aggressive behaviour. It was also predicted that more impulsive implicit cognitive processing would associate with aggressive behaviour whereas cognitively effortful implicit cognitive processing would not. Implicit aggressive cognitive processing was associated with increased dispositional aggression but not current reports of aggressive behaviour. Impulsive implicit cognitive processing of an aggressive nature predicted increased dispositional aggression whereas more cognitively effortful implicit cognitive aggression did not. The article concludes by outlining the importance of accounting for implicit cognitive processing among prisoners and the need to separate such processing into facets (i.e. impulsive vs. cognitively effortful). Implications for future research and practice in this novel area of study are indicated. Copyright © 2015 Elsevier Ltd. All rights reserved.

The relational neurobehavioral approach: can a non-aversive program manage adults with brain injury-related aggression without seclusion/restraint?

PubMed

Kalapatapu, Raj K; Giles, Gordon M

2017-11-01

The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. New data on interventions used in the RNA and on how the RNA interventions can be used with patients with acquired brain injury (ABI) who have differing levels of functional impairment are provided in this paper. The study was conducted over a 6-week period in a secure 65-bed program for individuals with ABI that is housed in two units of a skilled nursing facility (SNF). Implementation of the RNA was compared between two units that housed patients with differing levels of functional impairment (n = 65 adults). Since this was a hierarchical clustered dataset, Generalized Estimating Equations regression was used in the analyses. RNA interventions used to manage the 495 aggressive incidents included the following: Aggression ignored, Closer observation, Talking to patient, Reassurance, Physical distraction, Isolation without seclusion, Immediate medication by mouth, Holding patient. Different interventions were implemented differentially by staff based on level of functional impairment and without use of seclusion or mechanical restraint. The RNA can be used to non-aversively manage aggression in patients with brain injury and with differing levels of functional impairment. Programs adopting the RNA can potentially manage brain injury-related aggression without seclusion or mechanical restraint. Implications for Rehabilitation The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. RNA methods can be used to manage aggression in patients with brain injury who have differing levels of functional impairment. Successful implementation of the RNA may allow for the management of brain injury-related aggression without seclusion or mechanical restraint.

Jackson, Daisy R; Cappella, Elise; Neal, Jennifer Watling

2015-12-01

In a cross-sectional sample of African-American 2nd-4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers' social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children's direct and indirect connections in the classroom. Results of multilevel models indicate that network-based classroom aggression norms moderated relations between children's aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.

2010-04-01

Girl-to-girl aggression is increasingly being recognized as a health problem, and the number of teenage girls involved in serious fighting is on the rise. Research on the experiences of girl-to-girl aggression in marginalized girls who are out of the mainstream because of poor relationship skills and physical aggression is notably absent, yet this group is at heightened risk for persistent violence. In this study I used the interpretive phenomenological approach to study the lived experience of girl-to-girl aggression in girls who were marginalized and attending an alternative school because of physically aggressive behavior. Data were collected over a 4-month period by means of in-depth interviews and field notes. For this population, girl-to-girl aggression provided self-protection, expressed girls' identity, and was also a means to finding attachment, connection, and friendship. These findings have multidisciplinary implications for interventions with physically aggressive girls, including mentoring programs, in-school support groups, and exploration of a paradigm shift in the use of alternative schools.

Children’s Sympathy for Peers Who Are the Targets of Peer Aggression

PubMed Central

Leff, Stephen S.

2014-01-01

Although a goal of many aggression intervention programs is to increase children’s concern (often termed sympathy or empathy) for their peers as a means of ultimately reducing aggressive behavior, there are no measures specifically of children’s concern for peers who are the targets of peer aggression. A participatory action research (PAR) model was used to create a culturally-sensitive measure of urban African American children’s sympathy for peers who are the targets of physical aggression, relational or social aggression, verbal aggression, and property damage. In Study 1, 40 children (Mage =9.71 years; 47.5 % female) were interviewed about the types of incidents that lead them to feel sympathy for a peer. Based upon these findings, the 15-item Peer Sympathy Scale (PSS) was developed. In Study 2, the PSS was administered to 517 children (Mage=9.82 years; 47.4 % female) to examine the psychometric properties of the measure and to explore the association between children’s sympathy for their peers and their social behavior. Greater sympathy was associated with less overt and relational aggression according to both peer and teacher reports as well as with less oppositional-defiant behavior according to teacher reports. The clinical utility of the PSS as an outcome assessment tool for social skills intervention programs is discussed. PMID:22556114

Patient aggression is a common source of occupational violence in emergency departments. Staff attitudes regarding the causes for aggression influence the way they manage it. The Management of Clinical Aggression - Rapid Emergency Department Intervention is a 45 min educational program that aims to promote the use of de-escalation techniques and effective communication skills to prevent patient aggression. We sought to evaluate the impact of the program on staff attitudes regarding the prevention and early management of patient aggression. A mixed methods approach was used including a pre-test post-test survey of training participants and individual interviews with key stakeholders. The setting was public sector hospital emergency departments located in metropolitan and regional Victoria, Australia. A convenience sample of eighteen emergency departments was recruited via the Victorian Department of Health. Survey participants were nurses and midwives who were employed at the study sites. Interview participants were a purposive sample of nurse unit managers and trainers. The Management of Aggression and Violence Attitude Scale was administered to training participants immediately before and 6-8 weeks after training. Semi-structured telephone interviews with trainers and managers occurred 8-10 weeks after the intervention. Four hundred and seventy one participants completed the pre-test and post-test. Statistically significant shifts were observed in 5/23 items (Wilcoxon Signed Ranks Test: p ≤ 0.01). Despite training, participants were undecided if it was possible to prevent patient aggression, and continued to be unsure about the use of physical restraint. Twenty-eight (82.3%) of managers' and trainers' eligible to be interviewed provided their perceptions of the impact of the program. Overall, these perceptions were consistent with the significant shifts observed in the survey items. There was limited evidence to demonstrate that the program significantly

Disentangling functions of online aggression: The Cyber-Aggression Typology Questionnaire (CATQ).

Runions, Kevin C; Bak, Michal; Shaw, Thérèse

2017-01-01

Aggression in online contexts has received much attention over the last decade, yet there is a need for measures identifying the proximal psychological drivers of cyber-aggressive behavior. The purpose of this study was to present data on the newly developed Cyber-Aggression Typology Questionnaire (CATQ) designed to distinguish between four distinct types of cyber-aggression on dimensions of motivational valence and self-control. A sample 314 undergraduate students participated in the study. The results confirmed the predicted four-factor structure providing evidence for distinct and independent impulsive-aversive, controlled-aversive, impulsive-appetitive, and controlled-appetitive cyber-aggression types. Further analyses with the Berlin Cyberbullying Questionnaire, Reactive Proactive Aggression Questionnaire, and the Behavior Inhibition and Activation Systems Scale provide support for convergent and divergent validity. Understanding the motivations facilitating cyber-aggressive behavior could aid researchers in the development of new prevention and intervention strategies that focus on individual differences in maladaptive proximal drivers of aggression.

Aggression after traumatic brain injury: analysing socially desirable responses and the nature of aggressive traits.

PubMed

Dyer, Kevin F W; Bell, Rob; McCann, John; Rauch, Robert

2006-10-01

To compare patients with traumatic brain injury (TBI) with controls on sub-types of aggression and explore the role of social desirability. Quasi-experimental, matched-participants design. Sixty-nine participants were included in the study. The sample comprised a TBI group (n = 24), a spinal cord injury (SCI) group (n = 21) and an uninjured (UI) group of matched healthy volunteers (n = 24). Participants were given self-report measures of aggression, social desirability and impulsivity. Sixty-one independent 'other-raters' were nominated, who rated participant pre-morbid and post-morbid aggression. Using standardized norms, 25-39% of participants with TBI were classified as high average-very high on anger and 35-38% as high average-very high on verbal aggression. Other-raters rated participants with TBI as significantly higher on verbal aggression than SCI and UI participants. There were no differences between the groups on physical aggression. The TBI group also had higher levels of impulsivity than SCI and UI groups. Social desirability was a highly significant predictor of self-reported aggression for the entire sample. Impulsive verbal aggression and anger are the principal aggressive traits after brain injury. Physical aggression may present in extreme cases after TBI, but appears less prominent overall in this population. Social desirability, previously overlooked in research examining TBI aggression, emerged as an influential variable that should be considered in future TBI research.

Aggressive challenging behaviour and intellectual disability.

PubMed

Benson, Betsey A; Brooks, Whitney T

2008-09-01

The aim of this article is to review reports of aggressive challenging behaviour in individuals with intellectual disability from September 2006 to March 2008. Studies continued to demonstrate the prevalence and significance of aggressive challenging behaviour in persons with intellectual disability. Over half of the population engages in some form of aggression, but only a small number is responsible for frequent or severe acts. A publication that identified aggression profiles offered a promising new approach. Aggressive behaviour in adults often has multiple functions. The most frequently studied interventions were either behavioural or somatic. Parents learned skills to effectively intervene with their aggressive preschool child. Reviews of medication efficacy studies concluded that there was insufficient evidence to recommend a single medication. Psychiatrists agreed that medication should not be the first treatment option. In one study, a class of medication was found to reduce aggression, but not aggression with self-injury, or self-injury alone. Research on aggressive challenging behaviour requires assessment instruments that address the topography and severity of aggression. Identifying aggression types may clarify mixed results of previous research and improve treatment effectiveness. Greater access to effective, nonmedication treatments is needed.

Early-life adversity-induced long-term epigenetic programming associated with early onset of chronic physical aggression: Studies in humans and animals.

PubMed

Chistiakov, Dimitry A; Chekhonin, Vladimir P

2017-06-05

To examine whether chronic physical aggression (CPA) in adulthood can be epigenetically programmed early in life due to exposure to early-life adversity. Literature search of public databases such as PubMed/MEDLINE and Scopus. Children/adolescents susceptible for CPA and exposed to early-life abuse fail to efficiently cope with stress that in turn results in the development of CPA later in life. This phenomenon was observed in humans and animal models of aggression. The susceptibility to aggression is a complex trait that is regulated by the interaction between environmental and genetic factors. Epigenetic mechanisms mediate this interaction. Subjects exposed to stress early in life exhibited long-term epigenetic programming that can influence their behaviour in adulthood. This programming affects expression of many genes not only in the brain but also in other systems such as neuroendocrine and immune. The propensity to adult CPA behaviour in subjects experienced to early-life adversity is mediated by epigenetic programming that involves long-term systemic epigenetic alterations in a whole genome.

Aggression and violence and the achievement gap among urban minority youth.

Basch, Charles E

2011-10-01

To outline the prevalence and disparities of aggression and violence among school-aged urban minority youth, causal pathways through which aggression and violence adversely affects academic achievement, and proven or promising approaches for schools to address these problems. Literature review. Recent national data indicate that among students aged 12-18, approximately 628,200 violent crimes and 868,100 thefts occurred. Physical fighting was more commonly reported by Blacks and Hispanics (44.7% and 40.4%, respectively) than Whites (31.7%). In-school threats and injuries were nearly twice as prevalent in cities as in suburbs and towns or rural areas (10% vs 6% and 5%, respectively). Associations between exposure to and exhibition of aggression and violence and unfavorable educational outcomes are well documented. Causal pathways through which aggression and violence impede learning include cognition, school connectedness, and absenteeism. Disruptive classroom behavior is a well-recognized and significant impediment to teaching and learning. Compelling research has shown that various school-based programs can significantly reduce the nature and extent of aggressive and violent behaviors. Violence and aggressive behavior are highly and disproportionately prevalent among school-aged urban minority youth, have a negative impact on academic achievement by adversely affecting cognition, school connectedness, and absenteeism, and effective practices are available for schools to address this problem. Once the domain of criminal justice, aggression and violence are now recognized as an appropriate and important focus of the education and public health systems. Implementing evidence-based school policies and programs to reduce aggression and violence must be a high priority to help close the achievement gap. © 2011, American School Health Association.

Intra- Versus Intersex Aggression: Testing Theories of Sex Differences Using Aggression Networks.

PubMed

Wölfer, Ralf; Hewstone, Miles

2015-08-01

Two theories offer competing explanations of sex differences in aggressive behavior: sexual-selection theory and social-role theory. While each theory has specific strengths and limitations depending on the victim's sex, research hardly differentiates between intrasex and intersex aggression. In the present study, 11,307 students (mean age = 14.96 years; 50% girls, 50% boys) from 597 school classes provided social-network data (aggression and friendship networks) as well as physical (body mass index) and psychosocial (gender and masculinity norms) information. Aggression networks were used to disentangle intra- and intersex aggression, whereas their class-aggregated sex differences were analyzed using contextual predictors derived from sexual-selection and social-role theories. As expected, results revealed that sexual-selection theory predicted male-biased sex differences in intrasex aggression, whereas social-role theory predicted male-biased sex differences in intersex aggression. Findings suggest the value of explaining sex differences separately for intra- and intersex aggression with a dual-theory framework covering both evolutionary and normative components. © The Author(s) 2015.

Studying Sexual Aggression: A Review of the Evolution and Validity of Laboratory Paradigms

2018-01-01

Objective Researchers have endeavored for decades to develop and implement experimental assessments of sexual aggression and its precursors to capitalize on the many scientific advantages offered by laboratory experiments, such as rigorous control of key variables and identification of causal relationships. The purpose of this review is to provide an overview of and commentary on the evolution of these laboratory-based methods. Conclusions To date, two primary types of sexual aggression laboratory studies have been developed: those that involve behavioral analogues of sexual aggression and those that assess postulated precursors to sexually aggressive behavior. Although the study of sexual aggression in the laboratory is fraught with methodological challenges, validity concerns, and ethical considerations, advances in the field have resulted in greater methodological rigor, more precise dependent measures, and improved experimental validity, reliability, and realism. Because highly effective sexual aggression prevention strategies remain elusive, continued laboratory-based investigation of sexual aggression coupled with translation of critical findings to the development and modification of sexual aggression prevention programs remains an important task for the field.

Orpinas, Pamela; Home, Arthur M.

2009-01-01

The purpose of this article is to describe the GREAT (Guiding Responsibility and Expectations for Adolescents for Today and Tomorrow) Teacher Program, a prevention program for middle school teachers to deter students' aggressive behavior. It was developed on the basis of an ecologic understanding of aggression and on specific constructs of Social Cognitive Theory. The goals of the program were (1) to increase teacher awareness of different types of aggression, risk factors, role of the classroom teacher, and influence of the school climate on the child's behavior; (2) to develop strategies that will prevent aggression; (3) to improve teacher management skills to reduce power struggles and aggression; and (4) to enhance skills to assist students who are the targets of aggression. To accomplish these goals, teachers participated in a 12-hour workshop and 10 support group sessions. Training, manuals, and supervision were provided to maintain program integrity and to assure the quality of implementation. PMID:14732185

Research review: the importance of callous-unemotional traits for developmental models of aggressive and antisocial behavior.

PubMed

Frick, Paul J; White, Stuart F

2008-04-01

The current paper reviews research suggesting that the presence of a callous and unemotional interpersonal style designates an important subgroup of antisocial and aggressive youth. Specifically, callous-unemotional (CU) traits (e.g., lack of guilt, absence of empathy, callous use of others) seem to be relatively stable across childhood and adolescence and they designate a group of youth with a particularly severe, aggressive, and stable pattern of antisocial behavior. Further, antisocial youth with CU traits show a number of distinct emotional, cognitive, and personality characteristics compared to other antisocial youth. These characteristics of youth with CU traits have important implications for causal models of antisocial and aggressive behavior, for methods used to study antisocial youth, and for assessing and treating antisocial and aggressive behavior in children and adolescents.

The role of psychological maturity in direct and indirect aggressiveness in Spanish adolescents.

Understanding which factors are related to different kinds of aggressive behaviors in adolescents might help to improve violence-prevention programs for schools and families. Although some studies show that adolescents who are less psychologically mature tend to display more behavioral problems, few studies have been performed on the relationship between aggressive behavior and psychological maturity in adolescence, and no studies have focused specifically on indirect aggression. For this reason, the current research tests the role of psychological maturity in direct and indirect aggressiveness in a sample of 193 Spanish adolescents (49% boys and 51% girls) between 14 and 18 years old (M = 16.1, SD = 1.18). The results show that psychological maturity is related to both kinds of aggressiveness. In fact, less mature adolescents tend to show higher levels of direct aggression (r = -.22, p < .01) and indirect aggression (r = -.44, p < .01). More specifically, the dimensions of psychological maturity most related to aggressiveness are self-reliance and identity: self-reliance is the main predictor of indirect aggression (p < .01) and identity is the main predictor of direct aggression (p < .01). Moreover, overall psychological maturity is more related to indirect aggression in men than in women (p < .05), so the increase in psychological maturity implies a greater decrease of indirect aggression in men.

Research on exposure to television and movie violence suggests that playing violent video games will increase aggressive behavior. A metaanalytic review of the video-game research literature reveals that violent video games increase aggressive behavior in children and young adults. Experimental and nonexperimental studies with males and females in laboratory and field settings support this conclusion. Analyses also reveal that exposure to violent video games increases physiological arousal and aggression-related thoughts and feelings. Playing violent video games also decreases prosocial behavior.

2014-12-30

True fruit flies (Diptera: Tephritidae) include over 4000 species, many of which constitute enormous threats to fruit and vegetable production worldwide. A number of Tephritidae are lekking species, forming aggregations in which males fight to defend a small territory where they court females and mate. Male-male contests also occur in non-lekking species, characterized by resource defense polygyny. Tephritidae females display agonistic behavior to maintain single oviposition sites and reduce larval competition for food. Here, how, where, when and why aggressive interactions occur in Tephritidae flies is reviewed. A number of neglected issues deserving further research are highlighted, with a special focus on diel periodicity of aggression, cues evoking aggressive behavior, the role of previous experience on fighting success and the evolution of behavioral lateralization of aggressive displays. In the final section, future directions to exploit this knowledge in Integrated Pest Management, with particular emphasis on enhancement of Sterile Insect Technique and interspecific competitive displacement in the field are suggested.

2013-12-01

Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

2009-01-01

Consistent with the relative recency of research on workplace aggression and the considerable media attention given to high-profile incidents, numerous myths about the nature of workplace aggression have emerged. In this review, we examine these myths from an evidence-based perspective, bringing greater clarity to our understanding of the predictors of workplace aggression. We conclude by pointing to the need for more research focusing on construct validity and prevention issues as well as for methodologies that minimize the likelihood of mono-method bias and that strengthen the ability to make causal inferences.

Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing relational aggression on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of different questionnaires involving media and aggression at 3 different time points. Results revealed that viewing relational aggression on TV was longitudinally associated with future relational aggression. However, early levels of relational aggression did not predict future exposure to televised relational aggression. Conversely, there was a bidirectional relationship between TV violence and physical aggression over time. No longitudinal evidence was found for a general effect of viewing TV, as all significant media effects were specific to the type of aggression viewed. These results support the general aggression model and suggest that viewing relational aggression in the media can have a long-term effect on aggressive behavior during adolescence.

Toward a refined view of aggressive fantasy as a risk factor for aggression: interaction effects involving cognitive and situational variables.

Smith, Craig E; Fischer, Kurt W; Watson, Malcolm W

2009-01-01

Over three decades of research have established a positive connection between fantasizing about aggression and enacting aggression. Such findings have provided strong evidence against the catharsis view of aggressive fantasy. However, little attention has been paid to the potentially nuanced nature of the link between fantasy aggression and actual aggression. In the present article, we examined the influence of four variables in the aggressive fantasy-aggressive behavior link: gender, exposure to violence, fantasy absorption, and level of fantasy about harm befalling loved ones and the self (dysphoric fantasy). Using data from a diverse, community-based sample of 7-14-year olds and their mothers, we replicated the general finding that aggressive fantasy is positively associated with real-world aggressive behavior. However, we also found that the interaction of aggressive fantasy and exposure to violence related significantly to aggression, as did the relation between aggressive fantasy and dysphoric fantasy. When exposure to violence was low, even high levels of aggressive fantasizing did not predict aggressive behavior, and, when aggressive fantasizing was low, even high levels of exposure to violence did not predict aggressive behavior. Similarly, when dysphoric fantasy was high, the connection between fantasy aggression and real aggression was markedly attenuated. The implications of these findings for intervention efforts and future research are considered. Copyright 2009 Wiley-Liss, Inc.

The Department of Energy's Geothermal Program serves two broad purposes: 1) to assist industry in overcoming near-term barriers by conducting cost-shared research and field verification that allows geothermal energy to compete in today's aggressive energy markets; and 2) to undertake fundamental research with potentially large economic payoffs. The four categories of work used to distinguish the research activities of the Geothermal Program during FY 2000 reflect the main components of real-world geothermal projects. These categories form the main sections of the project descriptions in this Research Update. Exploration Technology research focuses on developing instruments and techniques to discover hidden hydrothermalmore » systems and to explore the deep portions of known systems. Research in geophysical and geochemical methods is expected to yield increased knowledge of hidden geothermal systems. Reservoir Technology research combines laboratory and analytical investigations with equipment development and field testing to establish practical tools for resource development and management for both hydrothermal reservoirs and enhanced geothermal systems. Research in various reservoir analysis techniques is generating a wide range of information that facilitates development of improved reservoir management tools. Drilling Technology focuses on developing improved, economic drilling and completion technology for geothermal wells. Ongoing research to avert lost circulation episodes in geothermal drilling is yielding positive results. Conversion Technology research focuses on reducing costs and improving binary conversion cycle efficiency, to permit greater use of the more abundant moderate-temperature geothermal resource, and on the development of materials that will improve the operating characteristics of many types of geothermal energy equipment. Increased output and improved performance of binary cycles will result from investigations in heat cycle research.« less

Neural Correlates of Aggressive Behavior in Real Time: a Review of fMRI Studies of Laboratory Reactive Aggression

Keedy, Sarah; Berman, Mitchell E.; Lee, Royce; Coccaro, Emil F.

2017-01-01

Purpose of review Aggressive behavior has adaptive value in many natural environments; however, it places substantial burden and costs on human society. For this reason, there has long been interest in understanding the neurobiological basis of aggression. This interest, and the flourishing of neuroimaging research in general, has spurred the development of a large and growing scientific literature on the topic. As a result, a neural circuit model of aggressive behavior has emerged that implicates interconnected brain regions that are involved in emotional reactivity, emotion regulation, and cognitive control. Recent findings Recently, behavioral paradigms that simulate provocative interactions have been adapted to neuroimaging protocols, providing an opportunity to directly probe the involvement of neural circuits in an aggressive interaction. Here we review neuroimaging studies of simulated aggressive interactions in research volunteers. We focus on studies that use a well-validated laboratory paradigm for reactive physical aggression and examine the neural correlates of provocation, retaliation, and evaluating punishment of an opponent. Summary Overall, the studies reviewed support the involvement of neural circuits that support emotional reactivity, emotion regulation, and cognitive control in aggressive behavior. Based on a synthesis of this literature, future research directions are discussed. PMID:29607288

An aggression policy that works.

Kitchener, Denby A; Sykes, Sharon R; McEwan, Allan G

2004-12-13

In 1999, a survey of the clinical staff in Royal Darwin Hospital showed that most instances of aggressive and abusive behaviour by patients or visitors occurring in the hospital went unreported because staff believed there would not be any follow-up investigation or action taken by management, Australia. In response, a hospital working party was formed to develop and implement an aggression management policy with practical effective strategies. The principal tool used was an Action Plan that delineated an immediate response to the aggression, as well as long-term strategies such as negotiated care and behaviour modification programs. An advocate is provided for the patient and debriefing for staff members. If the aggressive behaviour continues, early discharge of the patient could be initiated. The fundamental principle of the policy is to prevent fostering a culture of acceptance of aggressive behaviour through appropriate early intervention. In 2002, a follow-up survey showed that 82% of aggressive incidents were being reported and dealt with by management in a timely manner -- a significant improvement.

Maternal Depression and Childhood Aggression: Literature Review

Introduction Childbearing depression (CBD) and childhood aggression are serious and international problems that encumber public health. Although maternal depression has received much attention in the literature in the last three decades, clinically it remains under-diagnosed and under-treated, especially during pregnancy. As a result, many mothers and families are left to suffer its long-lasting physical and psychosocial effects. This article's aim is to review the current literature on whether CBD increases the likelihood of childhood aggression in children ages six years and younger. Methods Using keywords, an electronic search was performed using Cumulative Index of Nursing and Allied Health, PsycINFO, and PubMed databases. Search limits included the following: 2000-2010, English, peer-review, human, All Child: 0-18. From more than 2,000 search results, 13 articles were reviewed based on relevance to paper's inquiry and sample size greater than 50. Results In all, the articles agreed that depression in women increases the likelihood of early childhood aggression by causing negative parenting behaviors. However, this finding is tempered by a number of weaknesses in the quality of articles reviewed and by the complexity of the topic. Conclusion More research is needed to determine the etiology and interplay of mediating factors between CBD and childhood aggression. This could inform the study and implementation of effective and early prevention, screening, and treatment measures and programs for maternal depression and childhood aggression. PMID:22739482

Objective Sexual prejudice and masculine gender role stress were examined as mediators of the associations between adherence to different male gender norms and aggression toward sexual minorities. This study also sought to extend past research to a community sample and employ multiple methods to assess aggression. Method Participants were 199 heterosexual men between the ages of 18–30 who were recruited from a large southeastern United States city. Participants completed measures of adherence to male gender role norms, sexual prejudice, masculine gender role stress, and aggression toward sexual minorities. Results Associations between adherence to the status and antifemininity norms and aggression toward sexual minorities were mediated by sexual prejudice, but not masculine gender role stress. The portion of unique association between adherence to the antifemininity norm and aggression toward sexual minorities was about three times larger than the portion mediated by sexual prejudice and masculine gender role stress. Conclusions Findings provide the first multivariate evidence from a community-based sample for determinants of aggression toward sexual minorities motivated by gender role enforcement. These data support intervention programming and preventative intervention studies aimed at reducing sexual prejudice and facilitating less stereotypic attitudes about the male gender role, particularly surrounding the antifemininity norm.

Intergenerational Transmission of Aggression: Physiological Regulatory Processes

2015-01-01

Children who grow up in aggressive households are at risk of having problems with physiological regulation, but researchers have not investigated physiology as a mechanism in the intergenerational transmission of aggression. In this article, we posit that physiological regulation, particularly during stressful interpersonal interactions, may shed light on sensitivity to conflict, It can also inform our understanding of associations between childhood exposure to aggression in families of origin and aggression against partners in adolescence or adulthood. In support of this model, we highlight findings showing that childhood exposure to family aggression relates to physiological regulation across the life span, and that reactions to physiological stress concurrently relate to aggression against intimate partners. Emerging evidence from research on biological processes during stressful interpersonal interactions raises questions about what is adaptive for individuals from aggressive families, particularly as past family experiences intersect with the challenges of new relationships.

Valois, Robert F; Zullig, Keith J; Revels, Asa A

2017-04-01

In this cross-sectional study we explored relationships between aggressive and violent behaviors and emotional self-efficacy (ESE) in a statewide sample of public high school adolescents in South Carolina (N = 3836). The US Centers for Disease Control and Prevention Youth Risk Behavior Survey items on aggressive and violent behavior items and an adolescent ESE scale were used. Logistic regression analyses and multivariate models constructed separately, revealed significant race by sex findings. Results suggest that carrying a weapon to school (past 30 days) and being threatened or injured with a gun, knife, or club at school (past 12 months) were significantly associated (p < .05) with reduced ESE for specific race/sex groups. Results have implications for school- and community-based mental health services and social and emotional learning and aggression/violence prevention programs for adolescents. Measures of ESE as a component of comprehensive assessments of adolescent mental health, social and emotional learning and aggressive/violent behaviors in fieldwork, research, and program-evaluation efforts should be considered. © 2017, American School Health Association.

Aggression in pigtailed macaque (Macaca nemestrina) breeding groups affects pregnancy outcome

PubMed Central

Ha, James; Alloway, Hayley; Sussman, Adrienne

2011-01-01

Past research has shown that aggressive behaviors can affect female reproductive outcome in non-human primate captive breeding programs. In this study, aggressive behaviors were recorded in a colony of pigtailed macaque monkeys (Macaca nemestrina) and related to pregnancy outcome. For twenty-two weeks, behavioral data were collected from nine breeding groups, consisting of zero to one male (some males were removed after a cycle of conceptions for husbandry reasons) and four to eight females. Observations included all occurrences of eleven aggressive behaviors during 15-minute observation sessions, one to three times a week. Mean weekly aggression levels during the study period were determined for each group, as well as for each pregnancy. Aggression data were summarized with Principal Components Analyses (PCA). Results indicate that pigtailed macaque aggression falls into five distinctive categories: warn, engage, threaten, pursue, and attack. Breeding groups differed in their levels of aggression, even after controlling for group size, presence of a sire, and group stability. Levels of the five aggression categories were found to affect the probability that a pregnancy ended in either a natural birth of a live infant, a clinical intervention producing a live infant, or a nonviable outcome. The predictive value of aggression was significant when clinical interventions were included as possible reproductive outcomes, Behavioral observation of captive groups could identify “risk” conditions affecting pregnancy outcome and the requirement for clinical intervention.

Rasia-Filho, Alberto A; Giovenardi, Márcia; de Almeida, Rosa M M

2008-01-01

Aggression is conceived as a social behavior that, in conjunct with motor and visceral displays, is related with acts for obtaining a specific goal or is directed against threatening stimuli with the intention of causing harm, either for attack or defense. Here it is reviewed basic concepts and aspects for the classification of aggression, the behavioral displays regarded as aggressive in animal models, the basic neural circuits that are involved to them and the pharmacological approaches involving some neurotransmitters (5-HT, dopamine and GABA) and drugs that can be used to identify the neural basis of aggression and to modulate its expression. Drug patents are referred in the text. Data are based on experiments developed mainly with rodents; however, some research hypotheses that may well give some insights for the clinical sciences in men were also included.

2014-09-01

Aggression on haemodialysis units is a growing problem internationally that has received little research attention to date. Aggressive behaviour by patients or their relatives can compromise the safety and well-being of staff and other patients sharing a haemodialysis session. The objectives of the study were twofold: First, to identify the prevalance and nature of aggression on haemodialysis units; and second, to investigate factors that contribute to aggressive behaviour on haemodialysis units. A cross-sectional, sequential mixed method research design was adopted, with two research methods utilised. Incidents of aggressive behaviour were recorded over a 12-month period, using a renal version of the Staff Observation Aggression Scale. Six months after the incident data collection had commenced, semi-structured qualitative interviews were conducted with 29 multidisciplinary members of staff. Over 12 months, 74 aggressive incidents were recorded. The majority of incidents involved verbal aggression, and the perpetrators were a minority of patients, relatives and staff. Two patients were responsible for 38% of all incidents; both patients had mental health problems. Distinct temporal patterns to the aggressive behaviour were observed according to the day of the week and time of day. This study demonstrates that aggression is a significant problem on haemodialysis units, with verbal aggression most prevalent. The temporal patterns to aggression observed are related to the uniqueness of the haemodialysis setting, with a distinctly different treatment environment compared with other healthcare settings. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Examining Implicit and Explicit Evaluations of Sexual Aggression and Sexually Aggressive Behavior in Men Recruited Online.

Hermann, Chantal A; Nunes, Kevin L; Maimone, Sacha

2016-12-05

The purpose of the current study was to explore the relationship between implicit and explicit evaluations of sexual aggression and indicators of sexually aggressive behavior in samples of students and community men recruited online. Participants were male undergraduate students recruited online from a Canadian University (N = 150) and men recruited from the community via an online panel (N = 378). Participants completed measures of implicit and explicit evaluations of sexual aggression, cognitive distortions regarding rape, self-reported past sexually aggressive behavior, and self-reported proclivity to commit sexually aggressive behavior. We found that more positive explicit evaluations and more cognitive distortions were moderately to strongly associated with sexual aggression; however, this was not the case for implicit evaluations of rape. Our results suggest that explicit evaluations of sexual aggression and cognitive distortions may be relevant for understanding sexual aggression against adults, and that more research is needed exploring whether or not implicit evaluations are associated with sexually aggressive behavior. © The Author(s) 2016.

A theoretical framework for antigay aggression: Review of established and hypothesized effects within the context of the general aggression model⋆

PubMed Central

Parrott, Dominic J.

2008-01-01

Theory and research on antigay aggression has identified different motives that facilitate aggression based on sexual orientation. However, the individual and situational determinants of antigay aggression associated with these motivations have yet to be organized within a single theoretical framework. This limits researchers’ ability to organize existing knowledge, link that knowledge with related aggression theory, and guide the application of new findings. To address these limitations, this article argues for the use of an existing conceptual framework to guide thinking and generate new research in this area of study. Contemporary theories of antigay aggression, and empirical support for these theories, are reviewed and interpreted within the unifying framework of the general aggression model [Anderson, C.A. & Bushman, B.J. (2002). Human aggression. Annual Review of Psychology, 53, 27–51.]. It is concluded that this conceptual framework will facilitate investigation of individual and situational risk factors that may contribute to antigay aggression and guide development of individual-level intervention.

Verdon, Megan; Morrison, R S; Hemsworth, P H

2018-05-01

This experiment examined the effects of group composition on sow aggressive behaviour and welfare. Over 6 time replicates, 360 sows (parity 1-6) were mixed into groups (10 sows per pen, 1.8 m 2 /sow) composed of animals that were predicted to be aggressive (n = 18 pens) or groups composed of animals that were randomly selected (n = 18 pens). Predicted aggressive sows were selected based on a model-pig test that has been shown to be related to the aggressive behaviour of parity 2 sows when subsequently mixed in groups. Measurements were taken on aggression delivered post-mixing, and aggression delivered around feeding, fresh skin injuries and plasma cortisol concentrations at days 2 and 24 post-mixing. Live weight gain, litter size (born alive, total born, stillborn piglets), and farrowing rate were also recorded. Manipulating the group composition based on predicted sow aggressiveness had no effect (P > 0.05) on sow aggression delivered at mixing or around feeding, fresh injuries, cortisol, weight gain from day 2 to day 24, farrowing rate, or litter size. The lack of treatment effects in the present experiment could be attributed to (1) a failure of the model-pig test to predict aggression in older sows in groups, or (2) the dependence of the expression of the aggressive phenotype on factors such as social experience and characteristics (e.g., physical size and aggressive phenotype) of pen mates. This research draws attention to the intrinsic difficulties associated with predicting behaviour across contexts, particularly when the behaviour is highly dependent on interactions with conspecifics, and highlights the social complexities involved in the presentation of a behavioural phenotype.

Aggressive Delinquency among North American Indigenous Adolescents: Trajectories and Predictors

PubMed Central

Sittner, Kelley J.; Hautala, Dane

2016-01-01

Aggressive delinquency is a salient social problem for many North American Indigenous (American Indian, Canadian First Nations) communities, and can have deleterious consequences later in life. Yet there is a paucity of research on Indigenous delinquency. Group-based trajectory modeling is used to prospectively examine trajectories of aggressive delinquency over the course of adolescence using data from 646 Indigenous adolescents from a single culture, spanning the ages of 10 to 19. Five aggression trajectory groups were identified, characterized by different levels and ages of onset and desistence: non-offenders (22.1%), moderate desistors (19.9%), adolescent-limited offenders (22.2%), high desistors (16.7%), and chronic offenders (19.2%). Using the social development model of antisocial behavior, we selected relevant risk and protective factors predicted to discriminate among those most and least likely to engage in more aggressive behavior. Higher levels of risk (i.e., parent rejection, delinquent peers, substance use, and early dating) in early adolescence were associated with being in the two groups with the highest levels of aggressive delinquency. Positive school adjustment, the only significant protective factor, was associated with being in the lowest aggression trajectory groups. The results provide important information that could be used in developing prevention and intervention programs, particularly regarding vulnerable ages as well as malleable risk factors. Identifying those youth most at risk of engaging in higher levels of aggression may be key to preventing delinquency and reducing the overrepresentation of Indigenous youth in the justice system.

Adolescent Narcissism, Aggression, and Prosocial Behavior: The Relevance of Socially Desirable Responding.

PubMed

Barry, Christopher T; Lui, Joyce H L; Anderson, Alexandra C

2017-01-01

An important threat to validity in personality research pertains to an individual's motivation to respond in a socially desirable manner on self-report inventories. This issue was examined in this study in the context of narcissism, aggression, and prosocial behavior in a sample of at-risk adolescents. Participants were 161 adolescents (128 males, 29 females, 4 not reported) ranging in age from 16 to 19 years who were attending a residential program for youth who have dropped out of school. Overall, socially desirable response tendencies were negatively correlated with vulnerable narcissism and self-reported aggression. Moreover, low socially desirable responses strengthened the relation between narcissism and self-reported aggression. Socially desirable responding was not associated with self- or peer-reported prosocial behavior and did not moderate the relation between narcissism and prosocial behavior. These findings indicate that the relation between narcissism and aggression is attenuated by concerns with social desirability. However, further work is needed in broader samples of adolescents to more closely examine whether social desirability concerns actually mitigate aggression among some youth or signify underreporting of one's problem behaviors.

This study was to develop an aromatherapy hand massage program, and to evaluate the effects of lavender aromatherapy on cognitive function, emotion, and aggressive behavior of elderly with dementia of the Alzheimer's type. The Research design was a nonequivalent control group non-synchronized quasiexperimental study. Lavender aromatherapy was administrated to experimental group I for 2 weeks, jojoba oil massage was administrated to experimental group II for 2 weeks, and no treatment was administrated to the control group for 2 weeks. Data was analyzed using the chi(2)-test, ANOVA, repeated measures of ANCOVA and ANCOVA in the SPSS program package. 1. Experimental group I did not show significant differences in cognitive function in relation to the experimental group II and control group. 2. Experimental group I showed significant differences in emotion and aggressive behavior in relation to the experimental group II and control group. A Lavender aromatherapy hand massage program is effective on emotions and aggressive behavior of elderly with dementia of the Alzheimer's type.

Aggressive and nonaggressive children's moral judgments and moral emotion attributions in situations involving retaliation and unprovoked aggression.

Gasser, Luciano; Malti, Tina; Gutzwiller-Helfenfinger, Eveline

2012-01-01

The authors investigated 7- and 9-year-old children's moral understanding of retaliation as compared to unprovoked aggression with regard to their aggressive behavior status. Based on peer ratings, 48 children were selected as overtly aggressive and 91 as nonaggressive. Their moral understanding of retaliation and unprovoked aggression was assessed by an interview including questions about their moral judgments and emotion attributions. Aggressive children judged retaliations as less serious than did nonaggressive children. They also referred less often to the harmful consequences of retaliation and were more likely to excuse the retaliation because of the provocation. In unprovoked aggressive situations younger aggressive children, compared with the younger nonaggressive children, attributed more happiness to transgressors, more anger to victims, and less sadness to transgressors and victims. The results are discussed in terms of previous research on aggressive children's moral understanding of retaliation and unprovoked aggression.

Meeting potential sexual/romantic partners for mutual pleasure is one of the main reasons young adults go to bars. However, not all sexual contacts are positive and consensual, and aggression related to sexual advances is a common experience. Sometimes such aggression is related to misperceptions in making and receiving sexual advances while other times aggression reflects intentional harassment or other sexually aggressive acts. This study uses objective observational research to assess quantitatively gender of initiators and targets and the extent that sexual aggression involves intentional aggression by the initiator, the nature of responses by targets, and the role of third parties and intoxication. We analyzed 258 aggressive incidents involving sexual advances observed as part of a larger study on aggression in large capacity bars and clubs, using variables collected as part of the original research (gender, intoxication, intent) and variables coded from narrative descriptions (invasiveness, persistence, targets' responses, role of third parties). Hierarchical linear modeling analyses were used to account for nesting of incidents in evening and bars. Ninety percent of incidents involved male initiators and female targets, with almost all incidents involving intentional or probably intentional aggression. Targets mostly responded nonaggressively, usually using evasion. Staff rarely intervened; patron third parties intervened in 21% of incidents, usually to help the target but sometimes to encourage the initiator. initiators' level of invasiveness was related to intoxication of the targets, but not their own intoxication, suggesting intoxicated women were being targeted. Sexual aggression is a major problem in bars often reflecting intentional sexual invasiveness and unwanted persistence rather than misperceptions in sexual advances. Prevention needs to focus on addressing masculinity norms of male patrons and staff who support sexual aggression and better

Sexual Dating Aggression Across Grades 8 Through 12: Timing and Predictors of Onset

2013-01-01

Investigators have identified a number of factors that increase risk for physical and psychological dating abuse perpetration during adolescence, but as yet little is known about the etiology of sexual dating aggression during this critical developmental period. This is an important gap in the literature given that research suggests that patterns of sexual dating violence that are established during this period may carry over into young adulthood. Using a sample of 459 male adolescents (76% White, 19% Black), the current study used survival analysis to examine the timing and predictors of sexual dating aggression perpetration onset across grades 8 through 12. Risk for sexual dating aggression onset increased across early adolescence, peaked in the 10th grade, and desisted thereafter. As predicted based on the Confluence Model of sexual aggression, associations between early physical aggression towards peers and dates and sexual aggression onset were stronger for teens reporting higher levels of rape myth acceptance. Contrary to predictions, inter-parental violence, prior victimization experiences, and parental monitoring knowledge did not predict sexual dating aggression onset. Findings support the notion that risk factors may work synergistically to predict sexual dating aggression and highlight the importance of rape myth acceptance as a construct that should be addressed by violence prevention programs.

Cicchirillo, Vincent; Hmielowski, Jay; Hutchens, Myiah

2015-05-01

The purpose of this paper was to investigate the relationship between verbal aggression and uncivil media attention on political flaming. More specifically, this paper examines whether the use of uncivil media programming is associated with the perceived acceptability and intention to engage in aggressive online discussions (i.e., online political flaming) and whether this relationship varies by verbal aggression. The results show that individuals less inclined to engage in aggressive communication tactics (i.e., low in verbal aggression) become more accepting of flaming and show greater intention to flame as their attention to uncivil media increases. By contrast, those with comparatively higher levels of verbal aggression show a decrease in acceptance and intention to flame as their attention to these same media increases.

Aggression in children with behavioural/emotional difficulties: seeing aggression on television and video games.

2014-11-18

Mental health professionals are often asked to give advice about managing children's aggression. Good quality evidence on contributory environmental factors such as seeing aggression on television and in video games is relatively lacking, although societal and professional concerns are high. This study investigated possible associations between seeing aggression in such media and the aggressive behaviour of children attending specialist outpatient child and adolescent mental health services (CAMHS). In this mixed methods study, forty-seven British children aged 7-11 years with behavioural/emotional difficulties attending CAMHS and their carers participated in a survey; twenty purposively-selected children and a parent/carer of theirs participated in a qualitative study, involving semi-structured interviews, analysed using the Framework Analysis Approach; findings were integrated. Children attending CAMHS exhibit clinically significant aggression, of varying types and frequency. They see aggression in multiple real and virtual settings. Verbal aggression was often seen, frequently exhibited and strongly associated with poor peer relationships and low prosocial behaviour. Children did not think seeing aggression influences their own behaviour but believed it influences others. Carers regarded aggression as resulting from a combination of inner and environmental factors and seeing aggression in real-life as having more impact than television/video games. There is yet no definitive evidence for or against a direct relationship between aggression seen in the media and aggression in children with behavioural/emotional difficulties. Future research should take an ecological perspective, investigating individual, developmental and environmental factors. Carers, professional organisations and policy makers should address aggression seen in all relevant area of children's lives, primarily real-life and secondly virtual environments.

The Department of Energy's Geothermal Program serves two broad purposes: (1) to assist industry in overcoming near-term barriers by conducting cost-shared research and field verification that allows geothermal energy to compete in today's aggressive energy markets; and (2) to undertake fundamental research with potentially large economic payoffs. The four categories of work used to distinguish the research activities of the Geothermal Program during FY 2000 reflect the main components of real-world geothermal projects. These categories form the main sections of the project descriptions in this Research Update. Exploration Technology research focuses on developing instruments and techniques to discover hidden hydrothermalmore » systems and to explore the deep portions of known systems. Research in geophysical and geochemical methods is expected to yield increased knowledge of hidden geothermal systems. Reservoir Technology research combines laboratory and analytical investigations with equipment development and field testing to establish practical tools for resource development and management for both hydrothermal reservoirs and enhanced geothermal systems. Research in various reservoir analysis techniques is generating a wide range of information that facilitates development of improved reservoir management tools. Drilling Technology focuses on developing improved, economic drilling and completion technology for geothermal wells. Ongoing research to avert lost circulation episodes in geothermal drilling is yielding positive results. Conversion Technology research focuses on reducing costs and improving binary conversion cycle efficiency, to permit greater use of the more abundant moderate-temperature geothermal resource, and on the development of materials that will improve the operating characteristics of many types of geothermal energy equipment. Increased output and improved performance of binary cycles will result from investigations in heat cycle research.« less

Oxytocin and Aggression.

PubMed

de Jong, Trynke R; Neumann, Inga D

2017-09-02

The neuropeptide oxytocin (OT) has a solid reputation as a facilitator of social interactions such as parental and pair bonding, trust, and empathy. The many results supporting a pro-social role of OT have generated the hypothesis that impairments in the endogenous OT system may lead to antisocial behavior, most notably social withdrawal or pathological aggression. If this is indeed the case, administration of exogenous OT could be the "serenic" treatment that psychiatrists have for decades been searching for.In the present review, we list and discuss the evidence for an endogenous "hypo-oxytocinergic state" underlying aggressive and antisocial behavior, derived from both animal and human studies. We furthermore examine the reported effects of synthetic OT administration on aggression in rodents and humans.Although the scientific findings listed in this review support, in broad lines, the link between a down-regulated or impaired OT system activity and increased aggression, the anti-aggressive effects of synthetic OT are less straightforward and require further research. The rather complex picture that emerges adds to the ongoing debate questioning the unidirectional pro-social role of OT, as well as the strength of the effects of intranasal OT administration in humans.

How environmental and physiological signals interact to influence neural circuits underlying developmentally programmed social interactions such as male territorial aggression is poorly understood. We have tested the influence of sensory cues, social context, and sex hormones on progesterone receptor (PR)-expressing neurons in the ventromedial hypothalamus (VMH) that are critical for male territorial aggression. We find that these neurons can drive aggressive displays in solitary males independent of pheromonal input, gonadal hormones, opponents, or social context. By contrast, these neurons cannot elicit aggression in socially housed males that intrude in another male's territory unless their pheromone-sensing is disabled. This modulation of aggression cannot be accounted for by linear integration of environmental and physiological signals. Together, our studies suggest that fundamentally non-linear computations enable social context to exert a dominant influence on developmentally hard-wired hypothalamus-mediated male territorial aggression.

Neurobiological factors in aggressive behavior.

PubMed

Garza-Treviño, E S

1994-07-01

The author's aim was to review literature in the neurosciences and psychiatric clinical research reports about biological factors in aggression and the pathophysiological mechanisms that accompany aggression in neuropsychiatric syndromes. Studies were located through computer searches of relevant experimental reports and review articles mainly from the last 25 years. Several studies using neuroimaging and neurophysiological and neuropathological research techniques have identified lesions in the limbic structures, temporal lobes, and frontal lobes of the brain in abnormally aggressive individuals. Several reports have associated deficiency or dysregulation of serotonin with homicidal, suicidal, and impulsive behavior. However, few studies have focused on polypeptides or second messenger systems, although abnormalities in these systems have been reported in patients with neuropsychiatric syndromes who have shown aggressive behavior. Even fewer studies focus on the correlation of brain structures and metabolic markers. The understanding of aggressive behavior in psychiatric patients is fragmented. Some explanations are speculative and extrapolated to clinical psychiatric syndromes from experimental data on the neurophysiology of cats, rats, and other mammals. Identification of biochemical markers that can be used in predicting patients' response to pharmacological interventions may be the next step in developing more rational treatment of violent patients.

False memories for aggressive acts.

Can people develop false memories for committing aggressive acts? How does this process compare to developing false memories for victimhood? In the current research we used a simple false feedback procedure to implant false memories for committing aggressive acts (causing a black eye or spreading malicious gossip) or for victimhood (receiving a black eye). We then compared these false memories to other subjects' true memories for equivalent events. False aggressive memories were all too easy to implant, particularly in the minds of individuals with a proclivity towards aggression. Once implanted, the false memories were indistinguishable from true memories for the same events, on several dimensions, including emotional content. Implications for aggression-related memory more generally as well as false confessions are discussed. Copyright © 2013 Elsevier B.V. All rights reserved.

Female competition and aggression: interdisciplinary perspectives

PubMed Central

Stockley, Paula; Campbell, Anne

2013-01-01

This paper introduces a Theme Issue combining interdisciplinary perspectives in the study of female competition and aggression. Despite a history of being largely overlooked, evidence is now accumulating for the widespread evolutionary significance of female competition. Here, we provide a synthesis of contributions to this Theme Issue on humans and other vertebrates, and highlight directions for future research. Females compete for resources needed to survive and reproduce, and for preferred mates. Although female aggression takes diverse forms, under most circumstances relatively low-risk competitive strategies are favoured, most probably due to constraints of offspring production and care. In social species, dominance relationships and threats of punishment can resolve social conflict without resort to direct aggression, and coalitions or alliances may reduce risk of retaliation. Consistent with these trends, indirect aggression is a low cost but effective form of competition among young women. Costs are also minimized by flexibility in expression of competitive traits, with aggressive behaviour and competitive signalling tailored to social and ecological conditions. Future research on female competition and the proximate mediators of female aggression will be greatly enhanced by opportunities for interdisciplinary exchange, as evidenced by contributions to this Theme Issue.

Sexual narcissism and the perpetration of sexual aggression.

PubMed

Widman, Laura; McNulty, James K

2010-08-01

Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales-Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

Aggressive delinquency among north American indigenous adolescents: Trajectories and predictors.

PubMed

Sittner, Kelley J; Hautala, Dane

2016-01-01

Aggressive delinquency is a salient social problem for many North American Indigenous (American Indian, Canadian First Nations) communities, and can have deleterious consequences later in life. Yet there is a paucity of research on Indigenous delinquency. Group-based trajectory modeling is used to prospectively examine trajectories of aggressive delinquency over the course of adolescence using data from 646 Indigenous adolescents from a single culture, spanning the ages of 10-19. Five aggression trajectory groups were identified, characterized by different levels and ages of onset and desistence: non-offenders (22.1%), moderate desistors (19.9%), adolescent-limited offenders (22.2%), high desistors (16.7%), and chronic offenders (19.2%). Using the social development model of antisocial behavior, we selected relevant risk and protective factors predicted to discriminate among those most and least likely to engage in more aggressive behavior. Higher levels of risk (i.e., parent rejection, delinquent peers, substance use, and early dating) in early adolescence were associated with being in the two groups with the highest levels of aggressive delinquency. Positive school adjustment, the only significant protective factor, was associated with being in the lowest aggression trajectory groups. The results provide important information that could be used in developing prevention and intervention programs, particularly regarding vulnerable ages as well as malleable risk factors. Identifying those youth most at risk of engaging in higher levels of aggression may be key to preventing delinquency and reducing the over-representation of Indigenous youth in the justice system. © 2015 Wiley Periodicals, Inc.

School-based violence prevention programs have shown promise for reducing aggression and increasing children's prosocial behaviors. Prevention interventions within the context of urban after-school programs provide a unique opportunity for academic researchers and community stakeholders to collaborate in the creation of meaningful and sustainable violence prevention initiatives. This paper describes the development of a collaborative between academic researchers and community leaders to design a youth violence prevention/leadership promotion program (PARTNERS Program) for urban adolescents. Employing a community-based participatory research (CBPR) model, this project addresses the needs of urban youth, their families, and their community. Multiple strategies were used to engage community members in the development and implementation of the PARTNERS Program. These included focus groups, pilot testing the program in an after-school venue, and conducting organizational assessments of after-school sites as potential locations for the intervention. Community members and academic researchers successfully worked together in all stages of the project development. Community feedback helped the PARTNERS team redesign the proposed implementation and evaluation of the PARTNERS Program such that the revised study design allows for all sites to obtain the intervention over time and increases the possibility of building community capacity and sustainability of programs. Despite several challenges inherent to CBPR, the current study provides a number of lessons learned for the continued development of relationships and trust among researchers and community members, with particular attention to balancing the demand for systematic implementation of community-based interventions while being responsive to the immediate needs of the community.

Factors associated with rape as predictors of laboratory aggression against women.

Malamuth, N M

1983-08-01

This study examined the relation between factors associated with "real"-world aggression against women and laboratory aggression. In the first phase of the research, assessment was made of the attitudes about aggression against women and of the sexual responsiveness to rape of 42 male subjects. In the second phase of the research, which subjects believed was a totally independent experiment, aggression was assessed within a Buss paradigm. It was found that the factors assessed in the first phase successfully predicted men's laboratory aggression in the second research phase. The data are interpreted as supporting the construct validity of (a) theory that suggests that common factors underlie varied acts of aggression against women, (b) the measures designed to predict aggressive tendencies, and (c) the methodology of assessing aggression within a laboratory context.

Pupil-class determinants of aggressive and victim behaviour in pupils.

Mooij, T

1998-09-01

Aggressive behaviour in pupils is expressed in, e.g., bullying, sexual harassment, and violence. Different kinds of variables could be relevant in explaining a pupil's aggressive or victim behaviour. To develop a multilevel theoretical and empirical explanation for different kinds of aggressive and victim behaviour displayed by pupils in a classroom and school environment. A national survey was carried out to identify different kinds of aggressive and victim behaviour displayed by pupils and to assess other variables related to pupils, classes, and schools. A total of 1998 pupils from 100 third and fourth year classes attending 71 different secondary schools took part in the research. Data were analysed by a series of secondary multilevel analyses using the MLA-program. Being a boy, being more extravert, being more disagreeable, coming across fewer teachers with positive teaching behaviour, and attending a lower type of secondary school, help explain why someone is a perpetrator as such. Being a boy, being more disagreeable, being more emotionally unstable, being open to new ideas, and seeing more teachers as being strict, function as explanatory pupil variables for victim behaviour. Other pupil level variables determine more specific aggressive and victim behaviour aspects. Various other class level and school level variables are relevant, too. Personal and environmental pupil variables are more important than class variables but class variables are in turn more important than school variables in explaining a pupil's aggressive and victim behaviour.

The utility of Cox's Interaction Model to direct the assessment and prevention of adolescent aggression.

PubMed

DiNapoli, Pamela Pershing

2003-02-01

The current study of violence prevention is hampered by a lack of consensus on the definition of violence. There is, however, some agreement about the behavioral cues that may predict violent behavior such as aggression. Although it has been shown that individual-level variables (e.g., race, gender, and ethnicity) are correlated with aggressive behavior, it is clear that they alone are not explanatory of aggressive behavior. This article demonstrates how the Interaction Model of Client Health Behavior is an important health behavior framework for the assessment of aggression in adolescents, offering insight into the contextual nature of adolescent aggression. Victimization and witnessing of violence, frequently identified to be precursors of adolescent aggression in current epidemiologic studies, are examined within this framework. On the basis of the interactional nature of the phenomenon, necessary components for successful prevention programs are suggested. Finally, future research implications calling for a well-designed study that integrates individual and contextual variables with the use of this theory-driven explanatory framework are proposed.

McDonald, Kristina L; Benish-Weisman, Maya; O'Brien, Christopher T; Ungvary, Stephen

2015-12-01

Recent research has identified youth who utilize both aggressive and prosocial behavior with peers. Although the social values and motivations associated with aggression and prosocial behavior have been well studied, the values of youth who utilize both aggression and prosocial behavior are unknown. The current study identified groups of adolescents based on peer nominations of aggression and prosocial behavior from both Israel (n = 569; 56.94% Arab, 43.06% Jewish; 53.78% female) and the United States (n = 342; 67.54% African-American; 32.46% European-American; 50.88% female). Self-enhancement, self-transcendence, openness-to-change, and conservation values predicted behavioral group membership. Power values predicted membership in the aggressive group relative to the aggressive-prosocial, prosocial, and low-both groups. For Israeli boys, openness-to-change values predicted membership in the aggressive-prosocial group relative to the prosocial group. The values of aggressive-prosocial youth were more similar to the values of prosocial peers than to aggressive peers, suggesting that motivational interventions for aggressive-prosocial youth should differ in important ways than those for aggressive youth.

Pharmacology and pharmacogenetics of pediatric ADHD with associated aggression: a review.

PubMed

Patel, Bianca D; Barzman, Drew H

2013-12-01

Attention deficit hyperactivity disorder (ADHD) is often associated with symptoms of aggression in children and adolescents. Clinically, this is complex because aggression can be from hyperactivity and impulsivity, or could be a distinct symptom from a comorbid diagnosis. Past research has recommended first treating the primary disorder of ADHD. Stimulants are the most common treatment for pediatric ADHD, which can be helpful in decreasing aggressive behaviors. Alpha-adrenergic agonists and atomoxetine (ATX) are non-stimulant medications for ADHD and aggression, but more research is necessary to compare these drugs to stimulants. If aggressive symptoms do not improve from treating the primary disorder, aggression can be treated separately. Risperidone, lithium, valproic acid, clonidine, and guanfacine have shown positive results in reducing aggression, but studies including children with aggression and ADHD are limited. The variability in treatment tolerability in patients has stimulated research in pharmacogenetics for ADHD. Although this field is still emerging, research has found evidence supporting a link between the response rate of methylphenidate and the dopamine transporter (DAT1) and a link between the metabolism rate of atomoxetine and hepatic cytochrome 450 isozymes. Pharmacogenetics may be relevant to ADHD and associated aggression. Further research in pharmacogenetics will strive to identify patterns of genetic variations that can tailor individual treatments.

2016-01-01

Previous research has indicated that peer popularity is associated with aggressive behavior. However, it is not yet clear whether popularity is uniquely related to different functions of aggression. In this study, we examined associations between peer-perceived popularity, and reactive and proactive aggression using a cross-sectional and a longitudinal design. Yearly sociometric measures of popularity, and reactive and proactive aggression were gathered from 266 seventh and eight grade adolescents (Mage grade 7 = 12.80, SDage  = .40). Popularity was positively correlated with proactive aggression and negatively correlated with reactive aggression, both concurrently as over time. Curvilinear trends indicated that a significant minority of low versus high popular adolescents showed both functions of aggression. Somewhat stronger effects of popularity on proactive aggression were found for boys than girls. Stably popular adolescents showed the highest levels of proactive aggression, whereas stably unpopular youth showed the highest levels of reactive aggression. Implications and directions for future research are discussed. © 2015 Wiley Periodicals, Inc.

The Microgravity Research Program Office (MRPO) participated aggressively in Phase I of the International Space Station Program using the Russian Mir Space Station. The Mir Station offered an otherwise unavailable opportunity to explore the advantages and challenges to long duration microgravity space research. Payloads with both NASA and commercial backing were included as well as cooperative research with the Canadian Space Agency (CSA). From this experience, much was learned about dealing with long duration on orbit science utilization and developing new working relationships with our Russian partner to promote efficient planning, operations, and integration to solve complexities associated with a multiple partner program. Microgravity participation in the NASA Mir Program began with the first joint NASA Mir flight to the Mir Space Station. The earliest participation setup acceleration measurement capabilities that were used throughout the Program. Research, conducted by all Microgravity science disciplines, continued on each subsequent increment for the entire three-year duration of the Program. The Phase I Program included the Microgravity participation of over 30 Fluids, Combustion, Materials, and Biotechnology Sciences and numerous commercially sponsored research payloads. In addition to the research gained from Microgravity investigations, long duration operation of facility hardware was tested. Microgravity facilities operated on Mir included the Space Acceleration Measurement System (SAMS), the Microgravity Glovebox (MGBX), the Biotechnology System (BTS) and the Canadian Space Agency sponsored Microgravity Isolation Mount (MIM). The Russian OPTIZONE Furnace was also incorporated into our material science research. All of these efforts yielded significant and useful scientific research data. This paper focuses on the microgravity research conducted onboard the Mir space station. It includes the Program preparation and planning necessary to support this

Perpetration of Alcohol-Related Aggression by Male and Female College Students: An Examination of Overt and Relational Aggression.

Existing literature exemplifies the relationship between alcohol and overt aggression, especially for adult males. Less clear is the relationship between alcohol and aggression among male and female college students, in particular, the nature of this aggression and the co-occurrence of drinking and aggression on the same day (temporal proximity). This study examines the chronic and temporal nature of males' and females' alcohol-related aggression among college students. Two hundred fourteen students completed a web-based 7-day event-level survey measuring alcohol consumption and perpetration of physical aggression, verbal aggression, anger, and relational aggression over 4 weeks, resulting in 4,256 observations (days). The global analysis revealed students who are heavy drinkers are more likely to perpetrate all four forms of aggression, whereas the event-level analysis revealed that specific forms of aggression are associated with drinking at the time, while other forms were not linked to drinking occasions. Cross-tabulation revealed males and females were more likely to use verbal and physical aggression when drinking. For females, drinking was also associated with relational aggression and anger. Despite often being overlooked in research on aggression during emerging adulthood, relational aggression was prevalent. Discrepancies between the global and temporal analysis revealed factors other than alcohol might explain the relationship between chronic alcohol consumption and specific forms of aggression. This is one of the first event-level studies to show the temporal relationship between alcohol and relational aggression. The distinctions in the current study, exemplifying the diversity of alcohol-related aggression, are critical for understanding aggressive behavior, potential gender differences, and for developing interventions. The temporal relationship between alcohol and aggression suggests health interventions should target drinking and aggression

2018-07-01

The purpose of this study was to develop and provide initial validation for a measure of adult cyber intimate partner aggression (IPA): the Cyber Aggression in Relationships Scale (CARS). Drawing on recent conceptual models of cyber IPA, items from previous research exploring general cyber aggression and cyber IPA were modified and new items were generated for inclusion in the CARS. Two samples of adults 18 years or older were recruited online. We used item factor analysis to test the factor structure, model fit, and invariance of the measure structure across women and men. Results confirmed that three-factor models for both perpetration and victimization demonstrated good model fit, and that, in general, the CARS measures partner cyber aggression similarly for women and men. The CARS also demonstrated validity through significant associations with in-person IPA, trait anger, and jealousy. Findings suggest the CARS is a useful tool for assessing cyber IPA in both research and clinical settings.

Early Maladaptive Schemas and Aggression in Men Seeking Residential Substance Use Treatment

Shorey, Ryan C.; Elmquist, Joanna; Anderson, Scott; Stuart, Gregory L.

2015-01-01

Social-cognitive theories of aggression postulate that individuals who perpetrate aggression are likely to have high levels of maladaptive cognitive schemas that increase risk for aggression. Indeed, recent research has begun to examine whether early maladaptive schemas may increase the risk for aggression. However, no known research has examined this among individuals in substance use treatment, despite aggression and early maladaptive schemas being more prevalent among individuals with a substance use disorder than the general population. Toward this end, we examined the relationship between early maladaptive schemas and aggression in men in a residential substance use treatment facility (N = 106). Utilizing pre-existing patient records, results demonstrated unique associations between early maladaptive schema domains and aggression depending on the type of aggression and schema domain examined, even after controlling for substance use, antisocial personality, age, and education. The Impaired Limits domain was positively associated with verbal aggression, aggressive attitude, and overall aggression, whereas the Disconnection and Rejection domain was positively associated with physical aggression. These findings are consistent with social-cognitive models of aggression and advance our understanding of how early maladaptive schemas may influence aggression. The implications of these findings for future research are discussed. PMID:25897180

Kempes, M; de Vries, H; Matthys, W; van Engeland, H; van Hooff, J

2008-01-01

Various researchers distinguished two categories of aggressive behaviour, namely reactive and proactive aggression. Reactive aggression is an aggressive response to a perceived threat or provocation, whereas proactive aggression is behaviour that anticipates a reward. In the present study, including both a sample of disruptive behaviour disordered (DBD) and normal control (NC) children, we observed reactive and proactive aggressive behaviour during an experimental dyadic play session. DBD children showed more observed reactive and proactive aggression. Subsequently, we investigated whether the observed measures correlated with parent-rated measures of reactive and proactive aggression in. We distinguished in both NC and DBD children a subgroup showing a rise in cortisol level, i.e. responders, and a subgroup who did not show a rise in cortisol, i.e. non-responders. Results suggest that differences in the cortisol response affects the correspondence between observed and parent-rated reactive and proactive aggression since only DBD non-responders showed the expected correlations.

Impulsive versus Premeditated Aggression in the Prediction of Violent Criminal Recidivism

Swogger, Marc T.; Walsh, Zach; Christie, Michael; Priddy, Brittany M.; Conner, Kenneth R.

2015-01-01

Past aggression is a potent predictor of future aggression and informs the prediction of violent criminal recidivism. However, aggression is a heterogeneous construct and different types of aggression may confer different levels of risk for future violence. In this prospective study of 91 adults in a pretrial diversion program, we examined a) premeditated versus impulsive aggression in the prediction of violent recidivism during a one-year follow-up period, and b) whether either type of aggression would have incremental validity in the prediction of violent recidivism after taking into account frequency of past general aggression. Findings indicate that premeditated, but not impulsive, aggression predicts violent recidivism. Moreover, premeditated aggression remained a predictor of recidivism even with general aggression frequency in the model. Results provide preliminary evidence that the assessment of premeditated aggression provides relevant information for the management of violent offenders. PMID:25043811

2016-02-01

Individuals with fragile X syndrome (FXS), especially men, have long been described as presenting with significant behavioural challenges. Despite this known aspect of the phenotype, there has been little research exploring the prevalence, frequency, nature or consequences of aggressive behaviour in FXS. This study used survey methodology to gather caregiver reports on the types, frequency and severity of aggressive behaviour in 774 individuals with FXS. Based on caregiver report, nearly all (>90%) male and female individuals were reported to have engaged in some aggression over the previous 12 months, with a third of male cases and slightly fewer than 20% of female cases being described as engaging in moderate to severe aggression or being diagnosed or treated for aggression. Further, aggressive behaviours in male individuals were serious enough that 30% had caused injuries to caregivers and 22% had caused injuries to peers or friends. Sensory issues and hyperactivity were significant predictors of the frequency of aggressive acts, while sensory issues and anxiety were predictive of the severity of aggression. Traditional behaviour management techniques as well as medication was described as the most common and successful treatment options. Aggressive behaviours are a significant concern for a subsample of both male and female individuals with FXS. Given that sensory concerns were predictive of both the frequency and the severity of aggression suggests these behaviours may be a reactive means of escaping uncomfortable situations. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Yang, Fan; Chen, Xinyin; Wang, Li

2014-01-01

The primary purpose of the study was to examine the moderating effects of academic achievement on relations between aggressive behavior and social and psychological adjustment in Chinese children. A sample of children (N = 1,171; 591 boys, 580 girls; initial M age = 9 years) in China participated in the study. Two waves of longitudinal data were collected in Grades 3 and 4 from multiple sources including peer nominations, teacher ratings, self-reports, and school records. The results indicated that the main effects of aggression on adjustment were more evident than those of adjustment on aggression. Moreover, aggression was negatively associated with later leadership status and positively associated with later peer victimization, mainly for high-achieving children. The results suggested that consistent with the resource-potentiating model, academic achievement served to enhance the positive development of children with low aggression. On the other hand, although the findings indicated fewer main effects of adjustment on aggression, loneliness, depression, and perceived social incompetence positively predicted later aggression for low-achieving, but not high-achieving, children, which suggested that consistent with the stress-buffering model, academic achievement protected children with psychological difficulties from developing aggressive behavior. The results indicate that academic achievement is involved in behavioral and socioemotional development in different manners in Chinese children. Researchers should consider an integrative approach based on children's behavioral, psychological, and academic functions in designing prevention and intervention programs.

Huband, Nick; Ferriter, Michael; Nathan, Rajan; Jones, Hannah

2014-01-01

Background Aggression is a major public health issue and is integral to several mental health disorders. Antiepileptic drugs may reduce aggression by acting on the central nervous system to reduce neuronal hyper-excitability associated with aggression. Objectives To evaluate the efficacy of antiepileptic drugs in reducing aggression and associated impulsivity. Search methods We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, metaRegister of Controlled Trials (mRCT) and ClinicalTrials.gov to April 2009. We also searched Cochrane Schizophrenia Group’s register of trials on aggression, National Research Record and handsearched for studies. Selection criteria Prospective, placebo-controlled trials of antiepileptic drugs taken regularly by individuals with recurrent aggression to reduce the frequency or intensity of aggressive outbursts. Data collection and analysis Three authors independently selected studies and two authors independently extracted data. We calculated standardised mean differences (SMDs), with odds ratios (ORs) for dichotomous data. Main results Fourteen studies with data from 672 participants met the inclusion criteria. Five different antiepileptic drugs were examined. Sodium valproate/divalproex was superior to placebo for outpatient men with recurrent impulsive aggression, for impulsively aggressive adults with cluster B personality disorders, and for youths with conduct disorder, but not for children and adolescents with pervasive developmental disorder. Carbamazepine was superior to placebo in reducing acts of self-directed aggression in women with borderline personality disorder, but not in children with conduct disorder. Oxcarbazepine was superior to placebo for verbal aggression and aggression against objects in adult outpatients. Phenytoin was superior to placebo on the frequency of aggressive acts in male prisoners and in outpatient men including those with personality disorder, but not on the frequency of ‘behavioral incidents’ in

Prairie voles (Microtus ochrogaster) are socially monogamous rodents that form pair bonds—a behavior composed of several social interactions including attachment with a familiar mate and aggression toward conspecific strangers. Therefore, this species has provided an excellent opportunity for the study of pair bonding behavior and its underlying neural mechanisms. In this chapter, we discuss the utility of this unique animal model in the study of aggression and review recent findings illustrating the neurochemical mechanisms underlying pair bonding-induced aggression. Implications of this research for our understanding of the neurobiology of human violence are also discussed. PMID:22078479

Understanding the relationship between proactive and reactive aggression, and cyberbullying across United States and Singapore adolescent samples.

Ang, Rebecca P; Huan, Vivien S; Florell, Dan

2014-01-01

This study examined cyberbullying among adolescents across United States and Singapore samples. Specifically, the purpose of the investigation was to study the differential associations between proactive and reactive aggression, and cyberbullying across two cultures. A total of 425 adolescents from the United States (M age = 13 years) and a total of 332 adolescents from Singapore (M age = 14.2 years) participated in the study. Results of the moderator analyses suggested that nationality was not a moderator of the relationship between proactive aggression and cyberbullying, and between reactive aggression and cyberbullying. As expected, findings showed proactive aggression to be positively associated with cyberbullying, after controlling for reactive aggression, across both samples. Likewise, as hypothesized, reactive aggression and cyberbullying was not found to be significant after controlling for proactive aggression across both samples. Implications of these findings were discussed: (a) Proactive aggression is a possible risk factor for both bullying and cyberbullying; (b) proactive and reactive aggression could be argued to be distinct as they have different correlates-only proactive aggression contributed to cyberbullying after controlling for reactive aggression; (c) this research extends previous work and contributes toward cross-cultural work using similar and comparable measures across different samples; and (d) prevention and intervention programs targeted at proactive aggressive adolescents could adopt a two-pronged approach by changing mind sets, and by understanding and adopting a set of rules for Internet etiquette.

Approximately 73% of patients suffering from Borderline personality disorder (BPD) exhibit aggressive behaviour, which severely hinders therapeutic work and clinical improvement. Because the underlying mechanisms of aggression in BPD are not yet completely understood, additional research in this domain has a high clinical and scientific relevance. We employed a modified version of the Taylor Aggression Paradigm (mTAP), in order to examine for the first time whether this task can be used to differentiate between BPD patients and healthy controls with regard to reactive aggression. In the mTAP, the amount of money subtracted by a virtual opponent was categorized into ‘low’ (10–20 cents) and ‘high’ (80–100 cents) provocations, enabling us to compare how much money BPD patients and healthy controls subtracted (i.e., how aggressively participants responded) following high and low provocation trials. Our results showed that, compared to healthy controls, BPD patients showed higher overall aggression, higher aggression after high provocation trials, as well as a larger difference between high and low provocation trials. This finding was corroborated by a neuropsychological assessment, demonstrating higher levels of aggression and impulsivity in BPD patients. Interestingly, reactive aggression in the mTAP was positively correlated with symptom severity and impulsivity in BPD patients. We suggest that the mTAP provides a valuable tool allowing psychiatrists to quantify reactive aggression in BPD. Therefore, clinicians and researchers might consider this task, as a short experimental measure of reactive aggression, either in future studies or to aid diagnostic assessment during clinical practice.

The neurotransmitter serotonin (5-HT) has been linked to the underlying biological processes related to aggressive behaviour. However, only a few studies on this subject involving young people have been published so far. We aimed to investigate the effects of acute tryptophan depletion (ATD) on reactive aggression and decision-time for aggressive responses in a sample of young people with Attention deficit hyperactivity disorder (n = 20), a population at risk for aggressive behaviour. The study design was a double-blind within-subject crossover design. Aggression was assessed using a Point subtraction aggression game (PSAG) with high (HP) and low provocation (LP) trials 2.5 h after the intake of ATD and a tryptophan-balanced control condition. A chi-square comparison was used to identify the effect of ATD on increased aggression after LP. Boys were more likely to respond with an increased aggressive response after HP under ATD as represented by an increased relative risk and odds ratios. Girls had a higher relative risk than boys of an increased point subtraction under ATD after LP. No significant gender differences in decision-time were detected. An effect of ATD on increased aggression was found in the whole sample after LP. Research involving larger samples is needed to confirm the present preliminary findings. © 2012 John Wiley & Sons A/S.

The role of aggression-related early maladaptive schemas and schema modes in aggression in a prisoner sample.

Dunne, Ashley L; Gilbert, Flora; Lee, Stuart; Daffern, Michael

2018-05-01

Contemporary social-cognitive aggression theory and extant empirical research highlights the relationship between certain Early Maladaptive Schemas (EMSs) and aggression in offenders. To date, the related construct of schema modes, which presents a comprehensive and integrated schema unit, has received scant empirical attention. Furthermore, EMSs and schema modes have yet to be examined concurrently with respect to aggressive behavior. This study examined associations between EMSs, schema modes, and aggression in an offender sample. Two hundred and eight adult male prisoners completed self-report psychological tests measuring their histories of aggression, EMSs, and schema modes. Regression analyses revealed that EMSs were significantly associated with aggression but did not account for a unique portion of variance once the effects of schema modes were taken into account. Three schema modes, Enraged Child, Impulsive Child, and Bully and Attack, significantly predicted aggression. These findings support the proposition that schema modes characterized by escalating states of anger, rage, and impulsivity characterize aggressive offenders. In this regard, we call attention to the need to include schema modes in contemporary social-cognitive aggression theories, and suggest that systematic assessment and treatment of schema modes has the potential to enhance outcomes with violent offenders. © 2018 Wiley Periodicals, Inc.

Brain structures and neurotransmitters regulating aggression in cats: implications for human aggression.

PubMed

Gregg, T R; Siegel, A

2001-01-01

1. Violence and aggression are major public health problems. 2. The authors have used techniques of electrical brain stimulation, anatomical-immunohistochemical techniques, and behavioral pharmacology to investigate the neural systems and circuits underlying aggressive behavior in the cat. 3. The medial hypothalamus and midbrain periaqueductal gray are the most important structures mediating defensive rage behavior, and the perifornical lateral hypothalamus clearly mediates predatory attack behavior. The hippocampus, amygdala, bed nucleus of the stria terminalis, septal area, cingulate gyrus, and prefrontal cortex project to these structures directly or indirectly and thus can modulate the intensity of attack and rage. 4. Evidence suggests that several neurotransmitters facilitate defensive rage within the PAG and medial hypothalamus, including glutamate, Substance P, and cholecystokinin, and that opioid peptides suppress it; these effects usually depend on the subtype of receptor that is activated. 5. A key recent discovery was a GABAergic projection that may underlie the often-observed reciprocally inhibitory relationship between these two forms of aggression. 6. Recently, Substance P has come under scrutiny as a possible key neurotransmitter involved in defensive rage, and the mechanism by which it plays a role in aggression and rage is under investigation. 7. It is hoped that this line of research will provide a better understanding of the neural mechanisms and substrates regulating aggression and rage and thus establish a rational basis for treatment of disorders associated with these forms of aggression.

Physical aggressive resident behavior during hygienic care.

Farrell Miller, M

1997-05-01

Management of aggressive behavior has been identified as a concern for nursing staff who provide institutional care for cognitively impaired elderly. The Omnibus Reconciliation Act (OBRA '87) mandates a trial reduction in the use of chemical and physical restraints, and the development of nursing interventions for the management of behavioral disorders of institutionalized cognitively impaired elderly. Most skilled nursing facilities, however, are limited in their ability to provide environmental and behavioral programs to manage aggressive patient behavior. For the purposes of this study, physically aggressive behavior was identified as threatened or actual aggressive patient contact which has taken place between a patient and a member of the nursing staff. This study explored the nursing staff's responses to patient physical aggression and the effects that physical aggression had on them and on nursing practice from the perspective of the nursing staff. Nursing staff employed on one Dementia Special Care Unit (DSCU) were invited to participate. Interviews with nursing staff were analyzed using qualitative descriptive methods described by Miles and Huberman (1994). Nursing staff reported that they were subjected to aggressive patient behaviors ranging from verbal threats to actual physical violence. Nursing staff reported that showering a resident was the activity of daily living most likely to provoke patient to staff physical aggression. The findings revealed geropsychiatric nursing practices for the management of physically aggressive residents, and offered recommendations for improving the safety of nursing staff and residents on a secured DSCU.

2016-01-01

Background We hypothesized intrauterine growth restricted offspring (IUGR) demonstrate higher rates of aggression and higher dominance ranks than control (CTR) offspring with normal weight at term; if aggressive behavior is advantageous during resource scarcity, developmental programming may lead to an association between aggression and IUGR. Methods We studied 22 group-housed baboons (ages 3-5 years). CTR (male n=8, female n=5) mothers ate ad libitum. IUGR (male n=4, female n=5) mothers were fed 70% feed eaten by CTR mothers during pregnancy and lactation. Results IUGR showed higher rates of aggressive displays (p<0.01) and friendly displays (p<0.02). Dominance ranks and physical aggression rates did not differ between groups. Conclusions High rates of IUGR aggressive display might reflect developmental programming of behavioral phenotypes enhancing fitness. Friendly displays may reflect reconciliation. Potential mechanisms include neurodevelopment and learning. Exploration of IUGR as a risk factor for behavioral patterns is important for developing diagnostic and therapeutic strategies.

2008-05-01

Controlled trials have demonstrated that parents of children experiencing high levels of aggression benefit greatly from parent training programs. Several programs have shown a decrease in parental stress, an increase in parental confidence, and higher levels of prosocial behavior in children as shown by outcomes based on quantitative measures. However, less attention has been paid to the views and experiences of parents themselves about the impact of such programs on themselves, their children, and their parent-child relationships. The purpose of this qualitative study was to elicit and explore parents' perceptions of the effectiveness of the Incredible Years Parent Training Program. Following their participation in the Incredible Years Program, 37 parents completed a semistructured interview and completed demographic questionnaires. Data were analyzed employing a content analysis of the transcripts and descriptive statistics of the demographic data. Parents strongly valued the support offered within the group therapy process, reporting a decrease in their stress levels, an increase in their confidence, as well as observing positive changes in their children and in the parent-child relationship. The findings of this research illuminate possible underlying mechanisms for these observed changes. Specifically, when parents feel accepted, supported, and not blamed by healthcare professionals, they seem to be able to engage in self-reflection specifically related to their parenting styles. In turn, their ability to reflect in the group and make sense of their own thoughts, feelings, and behaviors seems to have a positive influence on the process of change in themselves, their children, and in their relationships with their children and other family members.

Parents’ Aggressive Influences and Children's Aggressive Problem Solutions with Peers

PubMed Central

Duman, Sarah; Margolin, Gayla

2009-01-01

This study examined children's aggressive and assertive solutions to hypothetical peer scenarios in relation to parents’ responses to similar hypothetical social scenarios and parents’ actual marital aggression. The study included 118 9−10 year old children, and their mothers and fathers. Children's aggressive solutions correlated with same-sex parents’ actual marital aggression. For children with mothers who exhibit low actual marital aggression, mothers’ aggressive solutions to hypothetical situations corresponded with children's tendencies to propose aggressive but not assertive solutions. In a 3-way interaction, fathers’ aggressive solutions to peer scenarios and marital aggression, combined, exacerbated girls’ aggressive problem solving, but had the opposite effect for boys. Discussion addresses the complexity, particularly with respect to parent and child gender combinations, in understanding parents’ aggressive influences on children's peer relationships.

2000-02-01

We report a study aimed at understanding the effects of classroom normative influences on individual aggressive behavior, using samples of 614 and 427 urban elementary school children. Participants were assessed with measures of aggressive behavior and normative beliefs about aggression. We tested hypotheses related to the effects of personal normative beliefs, descriptive classroom norms (the central tendency of classmates' aggressive behavior), injunctive classroom normative beliefs (classmates' beliefs about the acceptability of aggression), and norm salience (student and teacher sanctions against aggression) on longitudinal changes in aggressive behavior and beliefs. injunctive norms affected individual normative beliefs and aggression, but descriptive norms had no effect on either. In classrooms where students and teachers made norms against aggression salient, aggressive behavior diminished over time. Implications for classroom behavior management and further research are discussed.

Prenatal, perinatal, and adolescent exposure to marijuana: Relationships with aggressive behavior.

PubMed

Barthelemy, Olivier J; Richardson, Mark A; Cabral, Howard J; Frank, Deborah A

This manuscript reviews research exploring the relationship between prenatal, perinatal, and adolescent exposure to marijuana and aggressive behavior, including physical aggression. Areas of inquiry include animal research, as well as human research, on prenatal exposure and on marijuana use during adolescence. Potential psychosocial and psychopharmacological mechanisms are identified, as well as relevant confounds. The prenatal marijuana exposure literature provides minimal support for a direct relationship with aggressive behavior in childhood. The adolescent use literature suggests a marginal (at best) association between acute intoxication and aggressive behavior, and an association between chronic use and aggressive behavior heavily influenced by demographic variables, rather than direct, psychopharmacological mechanisms. Cannabis withdrawal symptoms also may include aggression and anger, but there is little evidence to suggest that these effects are large or specific to withdrawal from marijuana compared to other substances. This review will offer recommendations for clinical care and public policy, as well as important questions for future research. Copyright © 2016 Elsevier Inc. All rights reserved.

, estimated to comprise ~14% of the sample, followed a rising trajectory of high physical aggression. Best predictors before or at birth of the high physical aggression trajectory group, controlling for the levels of the other risk factors, were having young siblings (odds ratio [OR]: 4.00; confidence interval [CI]: 2.2–7.4), mothers with high levels of antisocial behavior before the end of high school (OR: 3.1; CI: 1.1–8.6), mothers who started having children early (OR: 3.1; CI: 1.4–6.8), families with low income (OR: 2.6; CI: 1.3–5.2), and mothers who smoked during pregnancy (OR: 2.2; CI: 1.1–4.1). Best predictors at 5 months of age were mothers’ coercive parenting behavior (OR: 2.3; CI: 1.1–4.7) and family dysfunction (OR: 2.2; CI: 1.2–4.1). The OR for a high-aggression trajectory was 10.9 for children whose mother reported both high levels of antisocial behavior and early childbearing. Conclusions Most children have initiated the use of physical aggression during infancy, and most will learn to use alternatives in the following years before they enter primary school. Humans seem to learn to regulate the use of physical aggression during the preschool years. Those who do not, seem to be at highest risk of serious violent behavior during adolescence and adulthood. Results from the present study indicate that children who are at highest risk of not learning to regulate physical aggression in early childhood have mothers with a history of antisocial behavior during their school years, mothers who start childbearing early and who smoke during pregnancy, and parents who have low income and have serious problems living together. All of these variables are relatively easy to measure during pregnancy. Preventive interventions should target families with high-risk profiles on these variables. Experiments with such programs have shown long-term impacts on child abuse and child antisocial behavior. However, these impacts were not observed in families with physical

The correspondence between the Staff Observation Aggression Scale-Revised and two other indicators for aggressive incidents.

PubMed

Tenneij, Nienke H; Goedhard, Laurette E; Stolker, Joost J; Nijman, Henk; Koot, Hans M

2009-08-01

Previous research has shown good psychometric properties of the Staff Observation Aggression Scale-Revised (SOAS-R). However, it has never been investigated what proportion of aggressive incidents occurring in facilities is documented with the SOAS-R. Furthermore, if incidents are underreported, the consequences for the categorization of clients into aggressive and nonaggressive subgroups based on the SOAS-R are unknown. To examine this, in four inpatient psychiatric facilities for adults with mild intellectual disabilities, aggressive incidents were documented with the SOAS-R and two other indicators of aggressive incidents: the daily staff reports on clients' behavior and reports on of the use of restraints. Less than half of the incidents documented with the staff and restraint reports were also documented with the SOAS-R. On the other way around, however, it was also found that a substantial proportion of incidents reported on SOAS-R forms were not documented in the daily staff reports, which points to a more general problem of underreporting aggressive behavior. Apart from that, categorization of clients into an aggressive and a nonaggressive subgroup with SOAS-R data collected during 1 month or longer corresponded largely with the categorization based on both other indicators. This study showed that underreporting of aggressive incidents is likely to occur with the SOAS-R, making the instrument less suitable to assess absolute aggression incidence in facilities. Still, the SOAS-R seems a good instrument to categorize clients into aggressive and nonaggressive subgroups. Ways to improve the compliance of the ward team to document all aggressive incidents are addressed in the Discussion section of this article.

Parental attitudes and aggression in the Emo subculture.

Chęć, Magdalena; Potemkowski, Andrzej; Wąsik, Marta; Samochowiec, Agnieszka

2016-01-01

A better functioning of adolescents involves proper relationships with parents, whereas negative relationships lead to aggressive behaviour. Young members of Emo subculture, characterised by deep emotional sensitivity, are particularly vulnerable to parental influence. The aim was to specify a relationship between parental attitudes and aggression among adolescents from the Emo subculture in comparison with a control group. 3,800 lower secondary school students took part in the introductory research. A target group constituted 41 people from the Emo subculture as well as a control group involving 48 people. A screening survey, the Parental Attitudes Scale, the Aggression Questionnaire and the author's questionnaire including questions concerning the functioning in the Emo subculture were used in the study. The results obtained in the research study suggest that there is a relationship between the indicated improper parental attitudes and aggressive behaviour among adolescents from the Emo subculture in comparison with the control group. In the Emo subculture, teenagers'aggressive behaviour is related to improper parental attitudes. It has been stated that mother's attitudes, irrespective of subculture, are much more strongly associated with the aggression among adolescents than father's attitudes. Moreover, aggressive behaviour in the Emo subculture occurs when father displays an excessively demanding attitude. A reduction of the level of almost all kinds of aggression manifested among teenagers from the Emo subculture is associated with mothers' attitude of acceptance. Mothers' autonomous attitude leads to an increase in the aggression in this group, whereas an inconsistent attitude of mothers fosters an increase in aggression among all teenagers.

Game location and aggression in rugby league.

2005-04-01

The present study examined the relationship between aggression and game location in rugby league. We videotaped a random sample of 21 professional rugby league games played in the 2000 Super League season. Trained observers recorded the frequency of aggressive behaviours. Consistent with previous research, which used territoriality theories as a basis for prediction, we hypothesized that the home team would behave more aggressively than the away team. The results showed no significant difference in the frequency of aggressive behaviours exhibited by the home and away teams. However, the away teams engaged in substantially more aggressive behaviours in games they lost compared with games they won. No significant differences in the pattern of aggressive behaviours for home and away teams emerged as a function of game time (i.e. first or second half) or game situation (i.e. when teams were winning, losing or drawing). The findings suggest that while home and away teams do not display different levels of aggression, the cost of behaving aggressively (in terms of game outcome) may be greater for the away team.

Longitudinal effects of increases and decreases in intimate partner aggression.

PubMed

Hammett, Julia F; Karney, Benjamin R; Bradbury, Thomas N

2018-04-01

Interventions aimed at reducing interpartner aggression assume that within-couple declines in aggression enhance individual and relational outcomes, yet reductions in aggression may fail to yield these benefits when other risk-generating mechanisms remain intact. The present study evaluates this possibility by investigating whether naturally observed within-couple changes in aggression are associated with improved individual and relational outcomes in the manner assumed by intervention programs. Drawing upon 4 waves of data collected at 9-month intervals from a community sample of 431 newlywed couples (76% Hispanic) living in low-income neighborhoods, Actor-Partner-Interdependence Modeling (APIM) and Structural Equation Modeling (SEM) indicated that levels of aggression at the outset of marriage had limited associations with later outcomes. Changes in aggression, however, were associated with subsequent marital outcomes, such that decreases in aggression were beneficial and increases in aggression were costly. Individuals who experienced increases in aggression worsened in their observed communication over time and reported greater increases in stress. Reports of stress early in marriage predicted escalations in aggression over time. Thus, helping couples to contain increases in aggression might be particularly consequential for their well-being.

An investigation of the mechanism underlying teacher aggression: Testing I3 theory and the General Aggression Model.

2017-12-01

Considerable research has investigated the deleterious effects of teachers responding aggressively to students who misbehave, but the mechanism underlying this dysfunctional behaviour remains unknown. This study investigated whether the mechanism underlying teacher aggression follows I 3 theory or General Aggression Model (GAM) metatheory of human aggression. I 3 theory explains exceptional, catastrophic events of human aggression, whereas the GAM explains common human aggression behaviours. A total of 249 Australian teachers participated in this study, including 142 primary school teachers (Mdn [age] = 35-39 years; Mdn [years teaching] = 10-14 years; 84% female) and 107 secondary school teachers (Mdn [age] = 45-49 years; Mdn [years teaching] = 15-19 years; 65% female). Participants completed four online self-report questionnaires, which assessed caregiving responsiveness, trait self-control, misbehaviour provocation, and teacher aggression. Analyses revealed that the GAM most accurately captures the mechanism underlying teacher aggression, with lower caregiving responsiveness appearing to indirectly lead to teacher aggression via higher misbehaviour provocation and lower trait self-control in serial, controlling for gender, age, years teaching, and current role (primary, secondary). This study indicates that teacher aggression proceeds from 'the person in the situation'. Specifically, lower caregiving responsiveness appears to negatively shape a teacher's affective, cognitive, and arousal states, which influence how they perceive and interpret student misbehaviour. These internal states, in turn, appear to negatively influence appraisal and decision processes, leading to immediate appraisal and impulsive actions. These results raise the possibility that teacher aggression is a form of countertransference. © 2017 The British Psychological Society.

Ji, Eun Sun; Jang, Mi Heui

2010-10-01

This study was done to explore the relationship between aggression and internet over-use, depression-anxiety, self-esteem, all of which are known to be behavior and psychological characteristics linked to "at-risk" children for aggression. Korean-Child Behavior Check List (K-CBCL), Korean-Internet Addiction Self-Test Scale, and Self-Esteem Scale by Rosenberg (1965) were used as measurement tools with a sample of 743, 5th-6th grade students from 3 elementary schools in Jecheon city. Chi-square, t-test, ANOVA, Pearson's correlation and stepwise multiple regression with SPSS/Win 13.0 version were used to analyze the collected data. Aggression for the elementary school students was positively correlated with internet over-use and depression-anxiety, whereas self-esteem was negatively correlated with aggression. Stepwise multiple regression analysis showed that 68.4% of the variance for aggression was significantly accounted for by internet over-use, depression-anxiety, and self-esteem. The most significant factor influencing aggression was depression-anxiety. These results suggest that earlier screening and intervention programs for depression-anxiety and internet over-use for elementary student will be helpful in preventing aggression.

Bullying: a stepping stone to dating aggression?

PubMed

Josephson, Wendy L; Pepler, Debra

2012-01-01

Bullying is the use of power and aggression to control and distress another. In this paper, we review research to explore whether the lessons learned in bullying provide a stepping stone to aggressive behavior in dating relationships. We start by considering definitions and a relationship framework with which to understand both bullying and dating aggression. We consider bullying from a developmental-contextual perspective and consider risk factors associated with the typical developmental patterns for bullying and dating aggression, including developmental and sociodemographic, individual attributes, and family, peer group, community, and societal relationship contexts that might lead some children and youths to follow developmental pathways that lead to bullying and dating aggression. We conclude by discussing implications for intervention with a review of evidence-based interventions.

Surveying managers to inform a regionally relevant invasive Phragmites australis control research program.

PubMed

Rohal, C B; Kettenring, K M; Sims, K; Hazelton, E L G; Ma, Z

2018-01-15

Managers of invasive species consider the peer-reviewed literature only moderately helpful for guiding their management programs. Though this "knowing-doing gap" has been well-described, there have been few efforts to guide scientists in how to develop useful and usable science. Here we demonstrate how a comprehensive survey of managers (representing 42 wetland management units across the Great Salt Lake watershed) can highlight management practices and challenges (here for the widespread invasive plant, Phragmites australis, a recent and aggressive invader in this region) to ultimately inform a research program. The diversity of surveyed organizations had wide-ranging amounts of Phragmites which led to different goals and approaches including more aggressive control targets and a wider array of control tools for smaller, private organizations compared to larger government-run properties. We found that nearly all managers (97%) used herbicide as their primary Phragmites control tool, while burning (65%), livestock grazing (49%), and mowing (43%) were also frequently used. Managers expressed uncertainties regarding the timing of herbicide application and type of herbicide for effective control. Trade-offs between different Phragmites treatments were driven by budgetary concerns, as well as environmental conditions like water levels and social constraints like permitting issues. Managers had specific ideas about the plant communities they desired following Phragmites control, yet revegetation of native species was rarely attempted. The results of this survey informed the development of large-scale, multi-year Phragmites control and native plant revegetation experiments to address management uncertainties regarding herbicide type and timing. The survey also facilitated initial scientist-manager communication, which led to collaborations and knowledge co-production between managers and researchers. An important outcome of the survey was that experimental results were

The present study examined sibling influence over reactive and proactive aggression in a sample of 452 same-sex twins (113 male dyads, 113 female dyads). Between and within siblings influence processes were examined as a function of relative levels of parental coercion and hostility to test the hypothesis that aggression contagion between twins occurs only among dyads who experience parental coerciveness. Teacher reports of reactive and proactive aggression were collected for each twin in kindergarten (M = 6.04 years; SD = 0.27) and in first grade (M = 7.08 years; SD = 0.27). Families were divided into relatively low, average, and relatively high parental coercion-hostility groups on the basis of maternal reports collected when the children were 5 years old. In families with relatively high levels of parental coercion-hostility, there was evidence of between-sibling influence, such that one twin’s reactive aggression at age 6 predicted increases in the other twin’s reactive aggression from ages 6 to 7, and one twin’s proactive aggression at age 6 predicted increases in the other twin’s proactive aggression from ages 6 to 7. There was also evidence of within-sibling influence such that a child’s level of reactive aggression at age 6 predicted increases in the same child’s proactive aggression at age 7, regardless of parental coercion-hostility. The findings provide new information about the etiology of reactive and proactive aggression and individual differences in their developmental interplay. PMID:25683448

Toward a nosology of human aggressive behavior.

PubMed

Eichelman, B; Hartwig, A

1993-01-01

General attempts have been made to catalog or categorize research literature on aggressive behavior. In the animal literature this category has been delineated by clearly observed and described patterns of behavior. These include offensive and defensive expressions in animals and the characterization of attack behaviors by typography into defensive and offensive. The human literature is considerably deficient in the description and categorization of human aggressive behavior. Current nosologies offer no utilitarian schema for characterizing violent behavior in clinical populations regarding the typography of the violence, its prediction, or guidance as to its treatment. The generation of databased nosologies may provide a mechanism for the development of research and clinically relevant nosologies based upon cluster analyses of treatment outcomes and behavioral characteristics. This strategy may provide a more effective approach for further research concerning clinical aggressive or destructive behaviors.

Skin conductance fear conditioning impairments and aggression: a longitudinal study.

2015-02-01

Autonomic fear conditioning deficits have been linked to child aggression and adult criminal behavior. However, it is unknown if fear conditioning deficits are specific to certain subtypes of aggression, and longitudinal research is rare. In the current study, reactive and proactive aggression were assessed in a sample of males and females when aged 10, 12, 15, and 18 years old. Skin conductance fear conditioning data were collected when they were 18 years old. Individuals who were persistently high on proactive aggression measures had significantly poorer conditioned responses at 18 years old when compared to others. This association was not found for reactive aggression. Consistent with prior literature, findings suggest that persistent antisocial individuals have unique neurobiological characteristics and that poor autonomic fear conditioning is associated with the presence of increased instrumental aggressive behavior. © 2014 Society for Psychophysiological Research.

The Relation Between Trait Mindfulness and Aggression in Men Seeking Residential Substance Use Treatment

PubMed Central

Shorey, Ryan C.; Anderson, Scott; Stuart, Gregory L.

2015-01-01

There has been an abundance of research in recent years on mindfulness, including mindfulness within individuals seeking substance use treatment. However, to date, there has been no research on whether trait mindfulness is associated with increased aggression among individuals seeking substance use treatment. Past research has demonstrated that individuals in substance use treatment evidence higher levels of aggression than non-substance abusers, and preliminary research has shown that trait mindfulness is inversely associated with aggression in non-substance-use treatment-seeking populations. The current study examined whether trait mindfulness was associated with aggression among men seeking residential substance use treatment (N = 116). Results demonstrated that lower trait mindfulness was associated with increased aggression (physical, verbal, and aggressive attitude). Moreover, this relation held for both verbal aggression and aggressive attitude after controlling for alcohol use, drug use, and age, all known predictors of aggression. Findings provide the first evidence that mindfulness is negatively associated with aggression among men in substance use treatment, which could have important implications for intervention. That is, mindfulness-based interventions may prove helpful for the treatment of both substance use and aggression. PMID:25192702

Recent scientific evidence demonstrates that many young men commonly resist condom use with their female sex partners and that both alcohol intoxication and a history of sexual aggression may increase the risk of condom use resistance (CUR). Using a community sample of heterosexual male non-problem drinkers with elevated sexual risk (N=311), this alcohol administration study examined the direct and indirect effects of intoxication and sexual aggression history on men's CUR intentions through a sexual risk analogue. State impulsivity, CUR-related attitudes, and CUR-related self-efficacy were assessed as mediators. Results demonstrated that alcohol intoxication directly increased CUR intentions, and sexual aggression history both directly and indirectly increased CUR intentions. These findings highlight the importance of addressing both alcohol use and sexual aggression in risky sex prevention programs, as well as indicate the continued worth of research regarding the intersection of men's alcohol use, sexual aggression, and sexual risk behaviors, especially CUR.

Acts of self-control are more likely to fail after previous exertion of self-control, known as the ego depletion effect. Research has shown that depleted participants behave more aggressively than non-depleted participants, especially after being provoked. Although exposure to nature (e.g., a walk in the park) has been predicted to replenish resources common to executive functioning and self-control, the extent to which exposure to nature may counteract the depletion effect on aggression has yet to be determined. The present study investigated the effects of exposure to nature on aggression following depletion. Aggression was measured by the intensity of noise blasts participants delivered to an ostensible opponent in a competition reaction-time task. As predicted, an interaction occurred between depletion and environmental manipulations for provoked aggression. Specifically, depleted participants behaved more aggressively in response to provocation than non-depleted participants in the urban condition. However, provoked aggression did not differ between depleted and non-depleted participants in the natural condition. Moreover, within the depletion condition, participants in the natural condition had lower levels of provoked aggression than participants in the urban condition. This study suggests that a brief period of nature exposure may restore self-control and help depleted people regain control over aggressive urges. © 2017 Wiley Periodicals, Inc.

The concept of aggression is important to nursing because further knowledge of aggression can help generate a better theoretical model to drive more effective intervention and prevention approaches. This paper outlines a conceptual analysis of aggression. First, the different forms of aggression are reviewed, including the clinical classification and the stimulus-based classification. Then the manifestations and measurement of aggression are described. Finally, the causes and consequences of aggression are outlined. It is argued that a better understanding of aggression and the causal factors underlying it are essential for learning how to prevent negative aggression in the future. PMID:15371137

Park, Jae Soon; Lee, Kyunghee

2012-12-01

Meager research has been carried out to determine the effectiveness of the token economy among patients behaving violently in mental hospitals. The purpose of this study was to examine the effectiveness of the Short-Term Token Economy (STTE) on violent behavior among chronic psychiatric in-patients. A nonequivalent control group design method was utilized. Participants in an experimental group (n=22) and control group (n=22) took part in this study from January to April, 2008. Observation on aggressive behavior among male in-patients in one hospital as a baseline was made during the week before the behavior modification program and measurement of aggressive behavior was done using the Overt Aggression Scale (OAS), which includes verbal attacks, property damage and physical attacks. The aggressive behavior scores of the experimental group decreased, those of the control group, scores showed an increase after the eight-week behavior modification program utilizing STTE. The results of the study indicate that STTE is effective in reducing the incidence of aggressive behavior among male in-patients in psychiatric hospitals. The outcome of this study should be helpful in reducing the use of coercive measures or psychoactive medication in controlling the violent behavior among in-patients in hospitals.

In 4 experimental studies, we show that customer verbal aggression impaired the cognitive performance of the targets of this aggression. In Study 1, customers' verbal aggression reduced recall of customers' requests. Study 2 extended these findings by showing that customer verbal aggression impaired recognition memory and working memory among employees of a cellular communication provider. In Study 3, the ability to take another's perspective attenuated the negative effects of customer verbal aggression on participants' cognitive performance. Study 4 linked customer verbal aggression to quality of task performance, showing a particularly negative influence of aggressive requests delivered by high-status customers. Together, these studies suggest that the effects of even minor aggression from customers can strongly affect the immediate cognitive performance of customer service employees and reduce their task performance. The implications for research on aggression and for the practice of customer service are discussed.

Sense of control and adolescents' aggression: The role of aggressive cues.

PubMed

Guo, Xucheng; Egan, Vincent; Zhang, Jianxin

2016-12-01

The misperception of aggressive cues is considered a risk factor for inducing adolescent aggression. Poor coping with life stress is also considered a major influence on aggression. The current study examined the relationship between subjective sense of control and adolescent aggression, considering influences upon the perception of these aggressive cues. In Study 1, 60 participants took part in a 2 (sense of control: high sense of control vs. low sense of control) × 2 (aggressive cue: aggressive vs. neutral) between-subjects contextual experiment. The result found that a lower sense of control led to an increase in adolescents' aggression; only in the low-sense-of-control condition did exposure to aggressive cues boost aggression. In Study 2, the catalytic effect of aggressive cues was further explored by an experiment in which 40 adolescents were randomly assigned to a low- or high-sense-of-control condition to test the importance of aggressive cues. The results suggest that adolescents in the low-sense-of-control condition show a higher salience for aggressive cues. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Alcohol and cannabis use have been implicated in aggression. Alcohol consumption is known to facilitate aggression, whereas a causal link between cannabis and aggression has not been clearly demonstrated. This study investigated the acute effects of alcohol and cannabis on subjective aggression in alcohol and cannabis users, respectively, following aggression exposure. Drug-free controls served as a reference. It was hypothesized that aggression exposure would increase subjective aggression in alcohol users during alcohol intoxication, whereas it was expected to decrease subjective aggression in cannabis users during cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21), and controls (n = 20) were included in a mixed factorial study. Alcohol and cannabis users received single doses of alcohol and placebo or cannabis and placebo, respectively. Subjective aggression was assessed before and after aggression exposure consisting of administrations of the point-subtraction aggression paradigm (PSAP) and the single category implicit association test (SC-IAT). Testosterone and cortisol levels in response to alcohol/cannabis treatment and aggression exposure were recorded as secondary outcome measures. Subjective aggression significantly increased following aggression exposure in all groups while being sober. Alcohol intoxication increased subjective aggression whereas cannabis decreased the subjective aggression following aggression exposure. Aggressive responses during the PSAP increased following alcohol and decreased following cannabis relative to placebo. Changes in aggressive feeling or response were not correlated to the neuroendocrine response to treatments. It is concluded that alcohol facilitates feelings of aggression whereas cannabis diminishes aggressive feelings in heavy alcohol and regular cannabis users, respectively.

A COGNITIVE PERSPECTIVE ON AGGRESSIVE MIMICRY

PubMed Central

JACKSON, ROBERT R.; CROSS, FIONA R.

2013-01-01

We use the term ‘aggressive mimic’ for predators that communicate with their prey by making signals to indirectly manipulate prey behaviour. For understanding why the aggressive mimic’s signals work, it is important to appreciate that these signals interface with the prey’s perceptual system, and that the aggressive mimic can be envisaged as playing mind games with its prey. Examples of aggressive mimicry vary from instances in which specifying a model is straight forward to instances where a concise characterisation of the model is difficult. However, the less straightforward examples of aggressive mimicry may be the more interesting examples in the context of animal cognition. In particular, there are spiders that prey on other spiders by entering their prey’s web and making signals. Web invasion brings about especially intimate contact with their prey’s perceptual system because the prey spider’s web is an important component of the prey spider’s sensory apparatus. For the web-invading spider, often there is also a large element of risk when practising aggressive mimicry because the intended prey is also a potential predator. This element of risk, combined with exceptionally intimate interfacing with prey perceptual systems, may have favoured the web-invading aggressive mimic’s strategy becoming strikingly cognitive in character. Yet a high level of flexibility may be widespread among aggressive mimics in general and, on the whole, we propose that research on aggressive mimicry holds exceptional potential for advancing our understanding of animal cognition.

To evaluate (a) the association between Internet addiction and aggressive behaviors, as well as the moderating effects of gender, school, and depression on this association; and (b) to evaluate the association between Internet activities and aggressive behaviors. A total of 9405 adolescents were recruited into this study and completed the questionnaires. Their aggressive behaviors, with or without Internet addiction, Internet activities, demographic data, with or without depression, self-esteem, family function, and the watching of violent TV were assessed. The results demonstrated that after controlling for the effects of shared associated factors and watching violent TV programs, adolescents with Internet addiction were more likely to have aggressive behaviors during the previous year. The association was more significant among adolescents in junior high schools than in senior high/vocational schools. Online chatting, adult sex Web viewing, online gaming, online gambling, and Bulletin Board System were all associated with aggressive behaviors. The results suggest that preventive programs for aggressive behaviors should pay attention to Internet addiction among adolescents. Also, intervention to prevent the effects of Internet addiction on aggressive behaviors should be conducted as early as possible.

Borderline Personality and Externalized Aggression

PubMed Central

Sansone, Lori A.

2012-01-01

Individuals with borderline personality disorder are diagnostically and clinically characterized by self-harm behavior, as indicated by the criterion in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision, “recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.” However, individuals with borderline personality disorder can display externalized aggressive behavior, as well. In an area characterized by considerably less research, empirical evidence indicates that individuals with borderline personality disorder may exhibit physical violence toward partners, physical violence toward known but nonintimate individuals, criminal behaviors that embody externalized violence (e.g., property damage), and, on very rare occasion, murderous behavior (either of family members or anonymous others through serial killing). Given this under-researched area, there are probably other types of externalized aggressive behaviors that have not been empirically revealed. However, externalized aggressive behaviors in individuals with borderline personality disorder clearly exist and need to be assessed in both psychiatric and primary care settings in an effort to promote safety of medical personnel and effective patient management.

Patterns of women's aggression against partners and others: broadening our understanding of violence.

PubMed

Rivera, Echo A; Kubiak, Sheryl P; Bybee, Deborah

2014-12-01

Research on women's aggression typically focuses on relational aggression. However, the study of violence must include multiple forms of violence such as aggression against partners and non-partner others, while also considering victimization experiences by partners and non-partners. The focus of this study is the multiple experiences of violence (perpetration and victimization) of women who are incarcerated. Incarcerated women are likely to experience higher rates of both than women in community settings, but most will be released in a brief period of time. Using a random sample (N = 580) we conducted cluster analyses to identify five patterns of women's aggression. Clusters varied depending on the target/s of aggression (i.e., partner and/or others), and type of aggression (i.e., physical and/or intimidation). Multinomial logistic regression was performed to determine the relationship between women's membership in a perpetration cluster and their victimization. Victimization history was related to an increased risk of perpetrating aggression, and varied depending on the target and type of aggression. Our findings provide support that research and interventions addressing women's use of aggression must also address their victimization history. Furthermore, results indicate that for some women, aggression towards partners and others is related. Future research should investigate multiple forms of aggression.

Intimate partner aggression and women's work outcomes.

Using conservation of resources theory, we examined the relationship between intimate partner aggression enacted against heterosexual women and 3 types of work-related outcomes for these women: withdrawal while at work (i.e., cognitive distraction, work neglect), withdrawal from work (i.e., partial absenteeism, intentions to quit), and performance. In Study 1, we compared withdrawal both at and from work across 3 clinically categorized groups of women (n = 50), showing that experiencing physical aggression is related to higher work neglect. We replicated and extended these findings in Study 2 using a community sample of employed women (n = 249) by considering the incremental variance explained by both physical aggression and psychological aggression on these same outcomes. Results showed that physical aggression predicted higher levels of withdrawal both at and from work, with psychological aggression predicting additional variance in partial absenteeism over and above the effects of physical aggression. Study 3 extended the model to include academic performance as an outcome in a sample of female college students (n = 122) in dating relationships. Controlling for the women's conscientiousness, psychological aggression predicted lower academic performance after accounting for the effects of physical aggression. We discuss theoretical and practical implications of these results, as well as directions for future research. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Signaling aggression.

PubMed

van Staaden, Moira J; Searcy, William A; Hanlon, Roger T

2011-01-01

From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

Enhancing Social Responsibility and Prosocial Leadership to Prevent Aggression, Peer Victimization, and Emotional Problems in Elementary School Children.

Leadbeater, Bonnie J; Thompson, Kara; Sukhawathanakul, Paweena

2016-12-01

Testing the theories that form the basis of prevention programs can enhance our understanding of behavioral change and inform the development, coordination, and adaptation of prevention programs. However, theories of change showing the linkages from intervention program components to risk or protective factors to desired outcomes across time are rarely specified or tested. In this 2-year longitudinal study, we test the theory that increases in two protective factors (i.e., children's prosocial leadership and their teachers' expectations of social responsibility) targeted by the WITS Programs (Walk Away, Ignore, Talk it Out, and Seek Help) would be associated with declines in peer victimization, aggression, and emotional problems. Participants included Canadian students, in grades 1-4 at baseline (n = 1329) and their parents and teachers. Consistent with our theory of change, variability in program implementation (adherence and integration) and in children's use of program skills (child responsiveness) are related to increases in both protective factors. Increases in these protective factors are associated with subsequent declines in children's aggression, victimization, and emotional problems. We discuss how enhancement of these protective factors may operate to improve child outcomes and the need for theory-based research to refine and improve the effectiveness of intervention strategies and to improve program scale-up. © Society for Community Research and Action 2016.

Growing up in armed groups: trauma and aggression among child soldiers in DR Congo

2013-01-01

Background Child soldiers are often both victims and perpetrators of horrendous acts of violence. Research with former child soldiers has consistently shown that exposure to violence is linked to trauma-related disorders and that living in a violent environment is correlated with enhanced levels of aggression. Objective To gain more insight into the experiences and the mental health status of former child soldiers, we conducted a survey with N=200 former child soldiers and adult combatants in the DR Congo. Methods We conducted semi-structured interviews concerning military experiences, experienced and perpetrated violence, and mental health. Results Former child soldiers reported more experienced and perpetrated violence, a greater severity of trauma-related suffering, as well as higher appetitive aggression than adult ex-combatants. Appetitive aggression was related to more perpetrated violence, higher military ranks, voluntary recruitment and higher rates of reenlistments in former child soldiers. Conclusions Our results indicate that growing up in an armed group is related to higher levels of trauma-related disorders and aggressive behavior. This may explain the challenge of reintegrating former child soldiers. It is thus important to consider mental health problems, particularly trauma-related disorders and aggressive behavior, of former child soldiers for designing adequate reintegration programs.

Caffeinated and Non-caffeinated Alcohol Use and Indirect Aggression: The Impact of Self-regulation

PubMed Central

Sheehan, Brynn E.; Linden-Carmichael, Ashley N.; Lau-Barraco, Cathy

2016-01-01

Research shows that heavier alcohol use is associated with physical aggression. Scant research has examined the way in which alcohol relates to other forms of aggression, such as indirect aggression (e.g., malicious humor, social exclusion). Given the possible negative consequences of indirect aggression and the limited evidence suggesting alcohol use can elicit indirectly aggressive responses, research is needed to further investigate the association between drinking behavior and indirect aggression. Additionally, specific alcoholic beverages, such as caffeinated alcoholic beverages (CABs; e.g., Red Bull and vodka), may potentiate aggression above the influence of typical use, thus warrant examination with regard to indirect aggression. One factor that may impact the strength of the alcohol-indirect aggression and CAB-indirect aggression relationships is one's level of self-regulation. Consequently, our study examined the relationships between (1) alcohol use and indirect aggression, (2) CAB use and indirect aggression, and (3) self-regulation as a moderator. Participants were 733 (67.6% female) undergraduate students who reported their CAB and alcohol use, self-regulation, and aggressive behaviors. Results revealed that heavier alcohol use was associated with more frequent indirect aggression after controlling for dispositional aggression. Heavier CAB use was related to more frequent indirect aggression after accounting for typical use and dispositional aggression. Self-regulation moderated these associations such that for those with lower self-regulation, greater alcohol and CAB consumption was associated with greater indirect aggression. Our findings suggest that heavier alcohol and CAB consumption may be risk factors for engaging in indirect aggression and this risk is impacted by one's regulatory control. PMID:26905765

Forgiveness and Consideration of Future Consequences in Aggressive Driving

PubMed Central

Moore, Michael; Dahlen, Eric R.

2008-01-01

Most research on aggressive driving has focused on identifying aspects of driver personality which will exacerbate it (e.g., sensation seeking, impulsiveness, driving anger, etc.). The present study was designed to examine two theoretically relevant but previously unexplored personality factors predicted to reduce the risk of aggressive driving: trait forgiveness and consideration of future consequences. The utility of these variables in predicting aggressive driving and driving anger expression was evaluated among 316 college student volunteers. Hierarchical multiple regressions permitted an analysis of the incremental validity of these constructs beyond respondent gender, age, miles driven per week, and driving anger. Both forgiveness and consideration of future consequences contributed to the prediction of aggressive driving and driving anger expression, independent of driving anger. Research on aggressive driving may be enhanced by greater attention to adaptive, potentially risk-reducing traits. Moreover, forgiveness and consideration of future consequences may have implications for accident prevention. PMID:18760093

The authors examined alcohol's effect on triggered displaced aggression, the hostile reaction to a second provoking person after provocation from a first. Participants consumed an alcoholic or a nonalcoholic beverage. Subsequently, one individual provoked all of them with moderate intensity. Then, 2 groups were studied: those who received or who failed to receive a second provocation of minimal intensity. Consistent with prior research, participants who received a second, minimal provocation displayed more aggression than those who did not. After participants drank alcohol, the magnitude of this difference was significantly greater, indicating that alcohol increases triggered displaced aggression.

Finigan-Carr, Nadine M.; Gielen, Andrea; Haynie, Denise L.; Cheng, Tina L.

2015-01-01

Although research suggests gender differences in both forms and functions of aggressive behavior, there has been limited research into these types among African American early adolescents. This study examined the types and patterns of aggression in girls and boys in that group. Participants were 452 predominantly African American middle school youth (50.4% girls) aged 11-13 (X = 11.97) enrolled in three urban public schools. Students were invited to participate in a school-based intervention designed to prevent aggressive and deviant behaviors. Assessments occurred pre- and post-intervention. Surveys were analyzed to identify gender differences in the levels and types of aggressive behaviors, as well as differences in predictors of aggressive behaviors. Predictors were measured at baseline; aggressive behaviors at follow-up. There were significant gender differences in types of aggressive behaviors and their predictors indicating a need to develop and implement more suitable, gender-tailored prevention and treatment approaches.

Hanish, Laura D.; Sallquist, Julie; DiDonato, Matthew; Fabes, Richard A.; Martin, Carol Lynn

2012-01-01

This study assessed girls’ and boys’ dominance-related behaviors (aggressive, commanding, submissive, and neutral behaviors) as they naturally occurred during interactions with male and female peers and evaluated the possibility that such behaviors elicit aggression from peers. Using a focal observational procedure, young girls’ and boys’ (N = 170; 54% boys) naturally occurring dominance-related behaviors and male and female peers’ aggressive responses to those behaviors were recorded multiple times each week across the academic year. Findings suggested that same-gender aggression occurred at similar rates as other-gender aggression once tendencies toward gender segregated play were controlled. Additionally, there were both gender-based similarities and differences in children’s use of dominance-related behaviors in peer interactions and as antecedents for peers’ aggression. The findings have implications for the literatures on aggression and gendered peer interactions. PMID:22369337

Emotion regulation and childhood aggression: longitudinal associations.

2012-12-01

Accumulating evidence suggests that emotion dysregulation is associated with psychopathology. This paper provides a review of recent longitudinal studies that investigate the relationship between emotion regulation and aggressive behavior in childhood age. While there is substantial evidence for assuming a close relation of emotion regulation and aggressive behavior, moderating and mediating factors like gender and peer rejection have been established. Furthermore, results suggest emotion dysregulation as an important risk factor of aggressive behavior. Several directions for future research are pointed out to further validate and refine the reviewed relationships.

Research on and intervention for child emotional abuse and emotional aggression toward children have been severely hampered because there have been no agreed-upon, clinically usable definitions. We have (a) proposed and field-tested a set of criteria to operationally define child emotional abuse for clinical settings and (b) used these criteria to design a parent-report measure of parental emotional aggression and child emotional abuse that could be used in research. In this paper, we review the development and field trials of these criteria for making substantiation decisions. Agreement between master reviewers and field decisions was extremely high in a 5-site development trial (96% agreement, κ=.89) and a 41-site dissemination trial (90% agreement, κ=.73). We compare these criteria to other research criteria in the literature. We then present data collected using a self-report measure designed to parallel these criteria from an anonymous online survey of US Air Force personnel and their spouses. The final sample (N=52,780) was weighted to be representative of the United States civilian population. The prevalence of parents' emotionally aggressive acts was much higher than the prevalence of emotional abuse (acts plus impact), but rates of parents' acts of emotional aggression were lower than those typically reported in the literature. Additional analyses tested for differential effects due to gender of perpetrator (i.e., mothers or fathers), age of victim, and clustering within families. These factors did not drive rates of aggression or abuse. In sum, the criteria developed and proposed appear to support reliable clinical decision making regarding child emotional abuse and can be translated to research survey tools that better capture the continuum of parents' emotional aggression and child emotional abuse than the measures that are currently available, advancing the state of the science with respect to child emotional abuse.

Men’s Facial Width-to-Height Ratio Predicts Aggression: A Meta-Analysis

PubMed Central

Haselhuhn, Michael P.; Ormiston, Margaret E.; Wong, Elaine M.

2015-01-01

Recent research has identified men’s facial width-to-height ratio (fWHR) as a reliable predictor of aggressive tendencies and behavior. Other research, however, has failed to replicate the fWHR-aggression relationship and has questioned whether previous findings are robust. In the current paper, we synthesize existing work by conducting a meta-analysis to estimate whether and how fWHR predicts aggression. Our results indicate a small, but significant, positive relationship between men’s fWHR and aggression. PMID:25849992

2015-02-01

Lateralisation (i.e. different functional and/or structural specialisations of the left and right sides of the brain) of aggression has been examined in several vertebrate species, while evidence for invertebrates is scarce. In this study, we investigated lateralisation of aggressive displays (boxing with forelegs and wing strikes) in the Mediterranean fruit fly, Ceratitis capitata. We attempted to answer the following questions: (1) do medflies show lateralisation of aggressive displays at the population-level; (2) are there sex differences in lateralisation of aggressive displays; and (3) does lateralisation of aggression enhance fighting success? Results showed left-biased population-level lateralisation of aggressive displays, with no consistent differences among sexes. In both male-male and female-female conflicts, aggressive behaviours performed with left body parts led to greater fighting success than those performed with right body parts. As we found left-biased preferential use of body parts for both wing strikes and boxing, we predicted that the left foreleg/wing is quicker in exploring/striking than the right one. We characterised wing strike and boxing using high-speed videos, calculating mean velocity of aggressive displays. For both sexes, aggressive displays that led to success were faster than unsuccessful ones. However, left wing/legs were not faster than right ones while performing aggressive acts. Further research is needed on proximate causes allowing enhanced fighting success of lateralised aggressive behaviour. This is the first report supporting the adaptive role of lateralisation of aggressive displays in insects.

Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

Agreeableness and alcohol-related aggression: the mediating effect of trait aggressivity.

PubMed

Miller, Cameron A; Parrott, Dominic J; Giancola, Peter R

2009-12-01

This study investigated the mediating effect of trait aggressivity on the relation between agreeableness and alcohol-related aggression in a laboratory setting. Participants were 116 healthy male social drinkers between 21 and 30 years of age. Agreeableness and trait aggressivity were measured using the Big Five Inventory and the Buss-Perry Aggression Questionnaire, respectively. Following the consumption of an alcohol or no-alcohol control beverage, participants completed a modified version of the Taylor Aggression Paradigm, in which electric shocks were received from and administered to a fictitious opponent during a competitive task. Aggression was operationalized as the proportion of the most extreme shocks delivered to the fictitious opponent under conditions of low and high provocation. Results indicated that lower levels of agreeableness were associated with higher levels of trait aggressivity. In turn, higher levels of trait aggressivity predicted extreme aggression in intoxicated, but not sober, participants under low, but not high, provocation. Findings highlight the importance of examining determinants of intoxicated aggression within a broader theoretical framework of personality.

Problematic alcohol use as a risk factor for cyber aggression within romantic relationships.

Cyber aggression has emerged as a modern form of intimate partner violence which has yet to undergo sufficient research necessary to identify risk factors that may increase the likelihood or severity of cyber aggressive behavior toward a relationship partner. Prior research offers contradictory findings pertaining to the relationship between problematic alcohol use and cyber aggression. We recruited 100 (40 female) adult participants through online crowdsourcing to complete a series of questionnaires assessing traditional partner violence, cyber aggression, and problematic alcohol use. Forty-two percent of the sample reported perpetrating cyber relational aggression and 35% reported perpetrating cyber privacy invasion during the year prior to study participation. Traditional partner violence was associated with both forms of cyber aggression. Problematic alcohol use was only associated with privacy invasion after accounting for demographic factors and traditional partner violence. Cyber aggression was prevalent among the current adult sample. Results suggest that problematic alcohol use is a risk factor for cyber privacy invasion but not cyber relational aggression. Findings add to and clarify the nascent, conflicting results that have emerged from prior research on alcohol-related cyber aggression.

2015-01-01

Manga, a type of graphic novel, represent a widely popular literary genre worldwide and are one of the fastest growing areas of the publishing arena aimed at adolescents in the United States. However, to our knowledge, there has been almost no empirical research examining content or effects of reading manga. This article consists of 2 studies. Study 1 represents a content analysis of aggressive behavior in best-selling manga aimed at adolescents. Results revealed that aggression was common and was often portrayed in ways that may influence subsequent behavior. Study 2 examined the relationship between reading manga and aggressive behavior in 223 adolescents. Manga readers were more physically aggressive than non-manga readers and also reported more peer relationships with lonely individuals and smaller groups. In addition, reading manga with particularly high levels of aggression was associated with physical aggression even after controlling for media violence exposure in other media. Implications regarding these findings are discussed.

Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend. About 25% of patients fulfill at least one criterion of aggressiveness. This result could be explained by a liquid Oncology which does not prioritize the patient as a moral subject in the clinical appointment. Medical care is oriented to necessities and must be articulated in a model focused on dignity and communication. Its implementation through Advanced Care Planning, consideration of patient's values and preferences, and Limitation of therapeutic effort are ways to reduce aggressiveness and improve clinical practice at the end of life. We need to encourage synergic and proactive attitudes, adding the best of cancer research with the best clinical care for the benefit of human being, moral subject and main goal of Medicine.

Aggression proneness: Transdiagnostic processes involving negative valence and cognitive systems.

PubMed

Verona, Edelyn; Bresin, Konrad

2015-11-01

Aggressive behavior is observed in persons with various mental health problems and has been studied from the perspectives of neuroscience and psychophysiology. The present research reviews some of the extant experimental literature to help clarify the interplay between domains of functioning implicated in aggression proneness. We then convey a process-oriented model that elucidates how the interplay of the Negative Valence and Cognitive System domains of NIMH's Research Domain Criteria (RDoC) helps explain aggression proneness, particularly reactive aggression. Finally, we report on a study involving event-related potential (ERP) indices of emotional and inhibitory control processing during an emotional-linguistic go/no-go task among 67 individuals with histories of violence and criminal offending (30% female, 44% African-American) who reported on their aggressive tendencies using the Buss-Perry Aggression Questionnaire. Results provide evidence that tendencies toward angry and aggressive behavior relate to reduced inhibitory control processing (no-go P3) specifically during relevant threat-word blocks, suggesting deterioration of cognitive control by acute or sustained threat sensitivity. These findings highlight the value of ERP methodologies for clarifying the interplay of Negative Valence and Cognitive System processes in aggression proneness. Copyright © 2015 Elsevier B.V.

Normative beliefs about aggression and cyber aggression among young adults: a longitudinal investigation.

PubMed

Wright, Michelle F; Li, Yan

2013-01-01

This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression. © 2013 Wiley Periodicals, Inc.

A Longitudinal Evaluation of the Positive Action Program in a Low-Income, Racially Diverse, Rural County: Effects on Self-Esteem, School Hassles, Aggression, and Internalizing Symptoms.

Positive Action is a school-based program that aims to decrease problem behaviors (e.g., violence, substance use) and increase positive behaviors (e.g., school engagement, academic achievement). Although a number of studies have shown that Positive Action successfully achieves these goals, few studies have evaluated the program's effectiveness in rural schools. Given that rural youth are at an increased risk for risky behaviors (e.g., violence, substance use), this is a critical gap in the existing Positive Action research base. The current study assesses the impact of Positive Action on change rates of self-esteem, school hassles, aggression, and internalizing symptoms in a group (N = 1246, 52% female) of ethnically/racially diverse (27% White, 23% African American, 12% mixed race/other, 8% Latino, 30% as American Indian) middle school youth (age range 9-20) located in two violent, low-income rural counties in North Carolina. One county engaged in Positive Action over the 3-year study window while the other county did not. Following multiple imputation and propensity score analysis, 4 two-level hierarchical linear models were run using each of the outcome measures as dependent variables. The results indicate that the program generates statistically significant beneficial effects for youth from the intervention county on self-esteem scores and school hassles scores. Although the program generates beneficial effects for intervention youth on the change in aggression scores, the finding is not statistically significant. The finding on the change in internalizing scores shows a non-significant detrimental effect: the youth from the comparison county have lower internalizing scores than those from the intervention county. Implications are discussed.

Aggression in the work environment of physiotherapists.

PubMed

Szczegielniak, Anna; Skowronek, Anna; Krysta, Krzysztof; Krupka-Matuszczyk, Irena

2012-09-01

Aggression in the medical environment can take on different forms. It can be inflicted both by patients and workmates and may also cause a rise of aggressive behavior performed by the physiotherapists themselves. The aim of the study was to evaluate possible danger that may occur in the working environment of physiotherapists as well as to assess the correlation between such factors as the length of professional experience and exposure to the aggression inflicted by patients and workmates in the workplace with the level of aggression occurring within the professional group of physiotherapists. The study was conducted among 50 physiotherapists from Opole and the Silesian Voivodships in Poland. Two types of questionnaires were used: the author's own questionnaire, assessing exposure of the physiotherapists to aggression in the workplace, and the Buss-Perry Aggression Questionnaire. The results were analyzed with the Statistica 8.0 application. 60% of participants suffered from patients' verbal aggression, 8% from physical aggression and 26% from the patients' emotional self-aggression at least twice a month. The study showed a minor correlation between the duration of the length of professional experience and the level of hostility (r=0.2; p>0.05). There is a considerable impact of negative emotions present in relations with workmates at the workplace causing mainly increase of general aggression among physiotherapists and hostility. Similarly, negative emotions that may appear in relations between psychiatrists and patients show a positive correlation with the level of general aggression developed by doctors. It can be observed that there is a huge impact of the impulsive behaviour and attitude (presented both by patients and workmates in the workplaces) on the appearance of aggressive actions by physiotherapists (especially anger and hostility). Further research in this field is needed.

Muscarine- and carbachol-induced aggressions: fear and irritable kinds of aggressions.

PubMed

Beleslin, D B; Samardzić, R

1977-12-28

In unaneasthetized and unrestrained cats, muscarine and carbachol were injected into the cerebral ventricles. The kind of aggressive behaviour depended on the cholinomimetic drug and was classified as fear and an irritable kind of aggression. Muscarine induced the fear kind of aggression. The aggressive behaviour was usually preceded by attempts to escape and the attack was relevant to the situation. For the attack the presence of some threatening agent was needed. The aggression was accompanied by intense motor but less autonomic activation. On the other hand, carbachol induced an irritable kind of aggression and had the following characteristics: for the attack the presence of some threatening agent was not needed; the attack was not relevant to the situation; the aggression was not preceded by attempts to escape; and the aggressive behaviour was accompanied by intense motor and autonomic activation. It is concluded that cholinoceptive mechanisms are involved in the control of aggressive behaviour.

Determinants of aggressive behavior: Interactive effects of emotional regulation and inhibitory control.

Hsieh, I-Ju; Chen, Yung Y

2017-01-01

Aggressive behavior can be defined as any behavior intended to hurt another person, and it is associated with many individual and social factors. This study examined the relationship between emotional regulation and inhibitory control in predicting aggressive behavior. Seventy-eight participants (40 males) completed self-report measures (Negative Mood Regulation Scale and Buss-Perry Aggression Questionnaire), a stop signal task, and engaged in a modified version of Taylor Aggression Paradigm (TAP) exercise, in which the outcome was used as a measure of direct physical aggression. We used a hierarchical, mixed-model multiple regression analysis test to examine the effects of emotion regulation and inhibitory control on physical reactive aggression. Results indicated an interaction between emotion regulation and inhibitory control on aggression. For participants with low inhibitory control only, there was a significant difference between high and low emotion regulation on aggression, such that low emotion regulation participants registered higher aggression than high emotion regulation participants. This difference was not found among participants with high inhibitory control. These results have implications for refining and targeting training and rehabilitation programs aimed at reducing aggressive behavior.

2015-03-01

Existing research on aggression tends to narrowly focus on peers; less is known about sibling aggression, most likely due to its historical acceptance. Aggression is characterized by its forms (i.e., physical vs. social or relational aggression) and its functions (i.e., the motivations behind the aggressive act and categorized as proactive vs. reactive aggression). We use data from a two-wave study of middle (n = 197; M age = 12.63 years at Wave 1) and older (n = 159; M age = 16.50 years at Wave 1) adolescents to assess the extent to which proactive and reactive functions of sibling aggression make unique or conditional contributions to adolescent adjustment (i.e., depression, delinquency, and substance use). We find that proactive sibling aggression increases risk for problem substance use and delinquent behavior, reactive sibling aggression increases risk for depressed mood and delinquent behavior, and such results are observed even with statistical adjustments for sociodemographic and family variables, stressful life events, and prior adjustment. Few conditional effects of proactive or reactive sibling aggression by sex or grade are observed; yet, for all three outcomes, the harmful effects of reactive sibling aggression are strongest among adolescents who report low levels of proactive sibling aggression. The results speak to the importance of understanding the proactive and reactive functions of sibling aggressive behaviors for adolescent adjustment. © The Author(s) 2014.

Does a booster intervention augment the preventive effects of an abbreviated version of the coping power program for aggressive children?

Booster interventions have been presumed to be important methods for maintaining the effects of evidence-based programs for children with behavioral problems, but there has been remarkably little empirical attention to this assumption. The present study examines the effect of a child-oriented booster preventive intervention with children who had previously received an abbreviated version (24 child sessions, 10 parent sessions) of the Coping Power targeted prevention program. Two hundred and forty-one children (152 boys, 89 girls) were screened as having moderate to high levels of aggressive behavior in 4th grade, then half were randomly assigned to receive the abbreviated Coping Power program in 5th grade, and half of the preventive intervention children were then randomly assigned to a Booster condition in 6th grade. The Booster sessions consisted of brief monthly individual contacts, and were primarily with the children. Five assessments across 4 years were collected from teachers, providing a three-year follow-up for all children who participated in the project. Results indicated that the abbreviated Coping Power program (one-third shorter than the full intervention) had long-term effects in reducing children's externalizing problem behaviors, proactive and reactive aggression, impulsivity traits and callous-unemotional traits. The Booster intervention did not augment these prevention effects. These findings indicate that a briefer and more readily disseminated form of an evidence-based targeted preventive intervention was effective. The findings have potential implications for policy and guidelines about possible intervention length and booster interventions.

Factors affecting aggression in South Korean middle school students.

Park, MiJeong; Choi, Jihea; Lim, Seung-Joo

2014-12-01

The study was undertaken to assess levels of aggression, and to determine factors affecting aggression among South Korean middle school students. A descriptive study was conducted using self-report questionnaires. The participants were 340 girls and boys from two middle schools and 302 questionnaires were used for the final data analysis. Aggression, academic stress, depression, self esteem, decision-making competency, and happiness were measured. Data were analyzed using descriptive statistics including t tests, one-way analysis of variance, Pearson's correlation coefficients and multiple regressions. Aggression had significant correlations with academic stress (r = .21, p < .001), depression (r = .43, p < .001), self esteem (r = -.25, p < .001), decision-making competency (r = -.25, p < .001), and happiness (r = -.21, p < .001). Mean score for aggression was 2.49 out of 5. Significant explanatory variables for aggression were grade (t = 4.39, p < .001), academic stress (t = 2.78, p = .006), and depression (t = 5.03, p < .001). The explanatory power of these factors was 26.9%, and this was statistically significant (F = 16.06, p < .001). Findings indicate that depression, academic stress, and grade (second grade) influence aggression. To decrease aggressive behavior, it is necessary to provide systematic and political programs in schools and local communities that can ameliorate negative emotional factors like depression and academic stress. Additionally, development of positive factors such as self esteem, decision-making skills, and happiness in middle school students is important to reduce aggression. Copyright © 2014.

Neurogenetics of Aggressive Behavior – Studies in Rodents

PubMed Central

Takahashi, Aki; Miczek, Klaus A.

2014-01-01

Aggressive behavior is observed in many animal species, such as insects, fish, lizards, frogs, and most mammals including humans. This wide range of conservation underscores the importance of aggressive behavior in the animals’ survival and fitness, and the likely heritability of this behavior. Although typical patterns of aggressive behavior differ between species, there are several concordances in the neurobiology of aggression among rodents, primates, and humans. Studies with rodent models may eventually help us to understand the neurogenetic architecture of aggression in humans. However, it is important to recognize the difference between the ecological and ethological significance of aggressive behavior (species-typical aggression) and maladaptive violence (escalated aggression) when applying the findings of aggression research using animal models to human or veterinary medicine. Well-studied rodent models for aggressive behavior in the laboratory setting include the mouse (Mus musculus), rat (Rattus norvegicus), hamster (Mesocricetus auratus), and prairie vole (Microtus ochrogaster). The neural circuits of rodent aggression have been gradually elucidated by several techniques e.g. immunohistochemistry of immediate-early gene (c-Fos) expression, intracranial drug microinjection, in vivo microdialysis, and optogenetics techniques. Also, evidence accumulated from the analysis of gene-knockout mice shows the involvement of several genes in aggression. Here we review the brain circuits that have been implicated in aggression, such as the hypothalamus, prefrontal cortex (PFC), dorsal raphe nucleus (DRN), nucleus accumbens (NAc), and olfactory system. We then discuss the roles of glutamate and γ-aminobutyric acid (GABA), major inhibitory and excitatory amino acids in the brain, as well as their receptors, in controlling aggressive behavior, focusing mainly on recent findings. At the end of this chapter, we discuss how genes can be identified that underlie

The validity of physical aggression in predicting adolescent academic performance.

PubMed

Loveland, James M; Lounsbury, John W; Welsh, Deborah; Buboltz, Walter C

2007-03-01

Aggression has a long history in academic research as both a criterion and a predictor variable and it is well documented that aggression is related to a variety of poor academic outcomes such as: lowered academic performance, absenteeism and lower graduation rates. However, recent research has implicated physical aggression as being predictive of lower academic performance. The purpose of this study was to examine the role of the 'Big Five' personality traits of agreeableness, openness to experience, conscientiousness, neuroticism and extraversion and physical aggression in predicting the grade point averages (GPA) of adolescent students and to investigate whether or not there were differences in these relationships between male and female students. A sample of 992 students in grades 9 to 12 from a high school in south-eastern USA as part of a larger study examining the students' preparation for entry into the workforce. The study was correlational in nature: students completed a personality inventory developed by the second author with the GPA information supplied by the school. Results indicated that physical aggression accounts for 16% of variance in GPA and it adds 7% to the prediction of GPA beyond the Big Five. The Big Five traits added only 1.5% to the prediction of GPA after controlling for physical aggression. Interestingly, a significantly larger amount of variance in GPA was predicted by physical aggression for females than for males. Aggression accounts for significantly more variance in the GPA of females than for males, even when controlling for the Big Five personality factors. Future research should examine the differences in the expression of aggression in males and females, as well as how this is affecting interactions between peers and between students and their teachers.

Our understanding of the biological basis of aggression in all vertebrates, including humans, has been built largely upon discoveries first made in birds. A voluminous literature now indicates that hormonal mechanisms are shared between humans and a number of avian species. Research on genetics mechanisms in birds has lagged behind the more typical laboratory species because the necessary tools have been lacking until recently. Over the past 30 years, three major technical advances have propelled forward our understanding of the hormonal, neural, and genetic bases of aggression in birds: (1) the development of assays to measure plasma levels of hormones in free-living individuals, or “field endocrinology”; (2) the immunohistochemical labeling of immediate early gene products to map neural responses to social stimuli; and (3) the sequencing of the zebra finch genome, which makes available a tremendous set of genomic tools for studying gene sequences, expression, and chromosomal structure in species for which we already have large datasets on aggressive behavior. This combination of hormonal, neuroendocrine, and genetic tools has established songbirds as powerful models for understanding the neural basis and evolution of aggression in vertebrates. In this chapter, we discuss the contributions of field endocrinology toward a theoretical framework linking aggression with sex steroids, explore evidence that the neural substrates of aggression are conserved across vertebrate species, and describe a promising new songbird model for studying the molecular genetic mechanisms underlying aggression.

This study examined the relationships among attitude toward violence, self-esteem, emotion dysregulation, anger, and aggression in community men and women and male inmates. Overall, 166 community men, 197 community women, and 100 male inmates completed a battery of questionnaires containing self-reported measures. Self-esteem and attitude toward violence were significant predictors of aggressive behavior, with emotion dysregulation mediating the relationship between self-esteem and the criterion variable. Anger mediated the relationship between emotion dysregulation and aggressive behavior only among community people. Among men, inmates reported a more favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, more aggressive behaviors, and a lower tendency to get angry. Women showed a less favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, and a higher tendency for anger than men, while no differences emerged for aggressive behavior. These findings suggest that self-related constructs and emotion regulation strategies represent key processes associated with aggressive behavior among all participants, while the role of anger is more prominent in community people. To reduce aggressive tendencies, treatment and prevention interventions might increase self-esteem, emotion regulation skills, and one's ability to direct anger toward other goals. Moreover, programs aimed at changing attitudes toward violence could be useful.

Does Humor Explain Why Relationally Aggressive Adolescents Are Popular?

Bowker, Julie C.; Etkin, Rebecca G.

2013-01-01

The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

Objective Drug use has been linked empirically with aggression and violence among youth in national and State of Hawai‘i samples. In addition, aggression and violence appear to be gendered experiences perceived differently by girls and boys. This paper explores the intersection of drug offers/drug refusals with aggression and violence with specific attention paid to gendered perceptions of drug use situations as a context for aggression and violence. Methods A qualitative study, in which fourteen sex-specific focus group discussions were held, focused on rural Native Hawaiian middle school students (N=64). Students were asked to discuss drug refusal strategies in a variety of drug offer contexts. Feminist theories and approaches were used to examine the role of aggression and violence in drug refusal as perceived by Native Hawaiian girls as compared to boys. Results Girls and boys differed in their perceptions of aggression and violence in drug offer situations, initially as evidenced by the extent to which the girls groups focused on the intersection of drugs and violence. Further, qualitative analyses reflected gender norms and stereotypes about aggression and violence perpetration, and girls' apparently unique concerns about sexual violence victimization. Conclusions Implications are discussed in terms of prevention research and practice, specifically in terms of school-based prevention curricula. PMID:27456534

The current study involved a short-term longitudinal study of young children (M = 44.56 months, SD = 11.88, N = 103) to test the prospective associations between peer victimization and aggression subtypes. Path analyses documented that teacher-reported physical victimization was uniquely associated with increases in observed physical aggression over time. The path model also revealed that teacher-reported relational victimization was uniquely associated with statistically significant increases in observed relational aggression over time. Ways in which these findings extend the extant developmental literature are discussed. © 2010 The Author. Child Development © 2010 Society for Research in Child Development, Inc.

2018-04-17

Previous research has demonstrated an association between aggressive challenging behaviour (CB) and reductions in work-related well-being for intellectual disability (ID) support staff. Much of this research has used subjective measures of CB. To examine whether exposure to aggressive CB is associated with reduced work-related well-being in staff working in ID residential settings across the UK. A cross-sectional analysis was undertaken as part of a randomised trial; 186 staff from 100 settings completed questionnaires on their CB self-efficacy, empathy, positive work motivation, and burnout. Objective measures of aggressive CB in the preceding 16 weeks were collected from each setting. There was little association between staff exposure to aggressive CB and work-related well-being. Clustering effects were found for emotional exhaustion and positive work motivation, suggesting these variables are more likely to be influenced by the environment in which staff work. The level of clustering may be key to understanding how to support staff working in ID residential settings, and should be explored further. Longitudinal data, and studies including a comparison of staff working in ID services without aggressive CB exposure are needed to fully understand any association between aggressive CB and staff well-being.

2016-01-01

Although much research examines the association between fathers’ relationship aggression and mothers’ parenting, little attention is given to mothers’ aggression, mutual aggression, or fathers’ parenting. Using a sample of coresiding couples from the Fragile Families and Child Wellbeing Study (N = 973), the authors examine the association between mothers’ and fathers’ relationship aggression, measured as frequency and perpetration-victimization types (mutual, mother-only, father-only), and mothers’ and fathers’ parenting. Fixed effects regression models show that fathers’ aggression—father-only or mutual—is positively related to mothers’ parenting stress, whereas father-only or mother-only aggression is related to fathers’ stress. For both parents, aggression perpetration is negatively related to their own engagement with children. Mother-only aggression is negatively related to mothers’ spanking and positively related to fathers’ spanking. These findings suggest the importance of examining both parents’ aggression and perpetrators’ as well as victims’ parenting to better understand the link between relationship aggression and parenting.

Objective While research has established some relationships between risk factors and specific suicide-related outcomes, in large part the extent to which suicidal ideation and attempts have different risk profiles is unclear. Using two theories of suicidal behavior to guide our hypotheses, we studied the relationship of outwardly-directed aggression to suicidal ideation and attempts in two high-risk samples. Method Participants in study one were 271 criminal offenders in a pretrial diversion program. Participants in study two were 892 psychiatric inpatients who participated in the MacArthur Violence Risk Assessment Study. Results In both studies, after controlling for relevant covariates, outwardly-directed aggression was associated with suicide attempts, but not ideation. Among psychiatric patients, further analyses revealed that outwardly-directed aggression was associated with planned, but not unplanned, suicide attempts. Conclusions That aggression is related to suicide attempts and not ideation is consistent with hypotheses based on both Joiner's (2005) interpersonal theory of suicidal behavior and theories based on a diathesis toward behavioral dysregulation (e.g., Mann, 2009). That aggression was associated with planned suicide attempts is consistent with Joiner's theory. Competing explanations for the results include a potential role of proactive aggression in suicide attempts, particularly planned attempts. PMID:26180654

2016-06-01

The living and working arrangements of migrant farmworkers in North Carolina are shaped by grower provided housing, codified by the US Department of Labor's H-2A temporary worker program. Growers typically dictate all facets about residences, living conditions, and even food acquirements. Farmworker camps likely contribute to aggression because of the forced relationships among a small group of people that live, work and recreate together for extended time periods. Participants in the study consisted of 371 farmworkers living in 183 camps. The Revised Conflict Tactics Scale was used to assess aggression among migrant farmworkers. Results indicated that aggressive acts were prevalent among the farmworkers, but the frequency of aggressive acts was low. The most common aggressive act was minor psychological aggression. Results also indicated that alcohol misuse was a common characteristic for both victims and perpetrators and the majority of aggressive acts occurred later in the agricultural season.

[Sexual aggression against girls and adult women--causes and consequences].

PubMed

Bitzer, J

2005-04-01

The causes of sexual aggression are multiple. Bioevolutionary rooted behavioral dispositions (sexual aggressiveness of men as a reproductive strategy) are enforced by specific male dominated structures of society and socially determined stereotypes of female roles which deter women from self determination of their sexuality; these macrosocial factors combine with individual conditions of socialization, in which violence plays an important role. With respect to the consequences of sexual aggression primary victimization (the trauma itself with physical and psychological harm) can be distinguished from secondary victimization (devaluation and mistrust in the social environment). The degree of negative health outcomes depends on risk factors like previous abuse, severity of the violent act, and lack of social support. Prevention must aim at changes of societal conditions that enhance sexual aggression and the establishment of programs for men and women at risk in which techniques of control of sexual aggression, attenuation and inhibition can be learnt.

2014-09-01

While there is a large body of research on the effects of being a direct target of workplace aggression, there is far less research on the vicarious experience of aggression at work, despite the fact that more people experience workplace aggression vicariously (i.e., observe it or hear about it) than they do directly. In this study, we develop and test a model of the effects of direct and vicarious exposure to aggression that is directed at employees by customers. Structural equation modeling provided support for the proposed model, in which direct and vicarious workplace aggression influences the perceived risk of future workplace aggression, which in turn affects organizational attachment (affective commitment and turnover intentions) and individual well-being (psychological and physical). Conceptual research and policy implications are discussed. © The Author(s) 2014.

Ferguson, Christopher J; San Miguel, Claudia; Garza, Adolfo; Jerabeck, Jessica M

2012-02-01

In 2011 the field of video game violence experienced serious reversals with repudiations of the current research by the US Supreme Court and the Australian Government as non-compelling and fundamentally flawed. Scholars too have been calling for higher quality research on this issue. The current study seeks to answer this call by providing longitudinal data on youth aggression and dating violence as potential consequences of violent video game exposure using well-validated clinical outcome measures and controlling for other relevant predictors of youth aggression. A sample of 165, mainly Hispanic youth, were tested at 3 intervals, an initial interview, and 1-year and 3-year intervals. Results indicated that exposure to video game violence was not related to any of the negative outcomes. Depression, antisocial personality traits, exposure to family violence and peer influences were the best predictors of aggression-related outcomes. The current study supports a growing body of evidence pointing away from video game violence use as a predictor of youth aggression. Public policy efforts, including funding, would best be served by redirecting them toward other prevention programs for youth violence. Copyright © 2011 Elsevier Ltd. All rights reserved.

Alcohol-related aggression-social and neurobiological factors.

PubMed

Beck, Anne; Heinz, Andreas

2013-10-01

Alcohol-related aggression and violence are a widespread cause of personal suffering with high socioeconomic costs. In 2011, nearly one in three violent acts in Germany was committed under the influence of alcohol (31.8%). The link between alcohol consumption and aggression is promoted by various interacting factors. In this review, based on a selective search for pertinent literature in PubMed, we analyze and summarize information from original articles, reviews, and book chapters about alcohol and aggression and discuss the neurobiological basis of aggressive behavior. Aggression is promoted both by the cognitive deficits arising in connection with acute or chronic alcohol use and by prior experience of violence in particular situations where alcohol was drunk. Only a minority of persons who drink alcohol become aggressive. On the other hand, alcohol abuse and dependence together constitute the second most commonly diagnosed cause of suicide (15-43%). Current research indicates that the individual tendency toward alcohol-induced aggression depends not just on neurobiological factors, but also on personal expectations of the effects of alcohol, on prior experience of violent conflicts, and on the environmental conditions of early childhood, especially social exclusion and discrimination. Gene-environment interactions affecting the serotonergic and other neurotransmitter systems play an important role. Potential (but not yet adequately validated) therapeutic approaches involve reinforcing cognitive processes or pharmacologically modulating serotonergic neurotransmission (and other target processes). Alcohol-related aggression has manifold social and neurobiological causes. Specific treatments must be tested in controlled trials.

A Positive Behavioral Approach for Aggression in Forensic Psychiatric Settings.

PubMed

Tolisano, Peter; Sondik, Tracey M; Dike, Charles C

2017-03-01

Aggression toward self and others by complex patients admitted to forensic psychiatric settings is a relatively common yet extremely difficult behavior to treat. Traditional interventions in forensic inpatient settings have historically emphasized control and management over treatment. Research over the past several years has demonstrated the value of behavioral and psychosocial treatment interventions to reduce aggression and to increase prosocial skill development in inpatient forensic population. Positive behavioral support (PBS) offers a comprehensive approach that incorporates the science of applied behavioral analysis (ABA) in support of patients with challenging behaviors, including aggression and violence. In this article, we describe a PBS model to treat aggression in forensic settings. PBS includes a comprehensive functional assessment, along with four basic elements: ecological strategies, positive programming, focused support strategies, and reactive strategies. Other key components are described, including data collection, staff training, fidelity checks to ensure correct implementation of the plan, and ongoing monitoring and revision of PBS strategies, according to treatment outcomes. Finally, a behavioral consultation team approach within the inpatient forensic setting is recommended, led by an assigned doctoral-level psychologist with specialized knowledge and training in behavioral methods. The behavioral consultation team works directly with the unit treatment team and the identified patient to develop, implement, and track a plan that may extend over several weeks to several months including transition into the community. PBS can offer a positive systemic impact in forensic inpatient settings, such as providing a nonpharmacologic means to address aggression, reducing the incidences of restraint and seclusion, enhancing staff proficiency in managing challenging patient presentations, and reducing recidivism when used as part of the bridge to

Graham, Kathryn; Bernards, Sharon; Osgood, D. Wayne; Abbey, Antonia; Parks, Michael; Flynn, Andrea; Dumas, Tara; Wells, Samantha

2014-01-01

Background Meeting potential sexual/romantic partners for mutual pleasure is one of the main reasons young adults go to bars. However, not all sexual contacts are positive and consensual, and aggression related to sexual advances is a common experience. Sometimes such aggression is related to misperceptions in making and receiving sexual advances while other times aggression reflects intentional harassment or other sexually aggressive acts. The present study uses objective observational research to assess quantitatively gender of initiators and targets and the extent that sexual aggression involves intentional aggression by the initiator, the nature of responses by targets, and the role of third parties and intoxication. Methods We analyzed 258 aggressive incidents involving sexual advances observed as part of a larger study on aggression in large capacity bars and clubs, using variables collected as part of the original research (gender, intoxication, intent) and variables coded from narrative descriptions (invasiveness, persistence, targets’ responses, role of third parties). Hierarchical Linear Modeling (HLM) analyses were used to account for nesting on incidents in evening and bars. Results 90% of incidents involved male initiators and female targets, with almost all incidents involving intentional or probably intentional aggression. Targets mostly responded nonaggressively, usually using evasion to end the incident. Staff rarely intervened; patron third parties intervened in 21% of incidents, usually to help the target but sometimes to encourage the initiator. Initiators’ level of invasiveness was related to intoxication of the targets but not their own intoxication, suggesting intoxicated women were being targeted. Conclusions Sexual aggression is a major problem in bars often reflecting intentional sexual invasiveness and unwanted persistence rather than misperceptions in sexual advances. Prevention needs to focus on addressing masculinity norms of male

Family Functioning and High Risk Adolescents' Aggressive Behavior: Examining Effects by Ethnicity.

PubMed

Henneberger, Angela K; Varga, Shannon M; Moudy, Alyssa; Tolan, Patrick H

2016-01-01

The relationship between family functioning and adolescents' physical aggression has been well established, but whether these relationships might differ by ethnicity has received less attention. Ethnic variations may be important for targeting prevention programs to specific youth and families. This study examined the longitudinal relationship between family cohesion, parental monitoring, and physical aggression using data from the Multisite Violence Prevention Project sample of high-risk youth (elevated aggression). Participants were 1,232 high-risk middle school students (65% male; 70% African American; 15% Hispanic). Meaningful demographic variations were identified. After controlling for intervention condition and study site, family cohesion was significantly negatively related to physical aggression, more so for Hispanic youth. Parental monitoring was negatively associated with physical aggression for African American youth only. Our findings point to the importance of developing culturally sensitive family interventions to prevent physical aggression in middle school.

Are all perpetrators alike? Comparing risk factors for sexual coercion and aggression.

PubMed

DeGue, Sarah; DiLillo, David; Scalora, Mario

2010-12-01

The present study developed and contrasted predictive models of male nonphysical sexual coercion (e.g., verbal pressure or manipulation) and physical sexual aggression (e.g., incapacitation, physical force, or threats) using a sample of 369 incarcerated males to identify shared and unique risk factors for each form of sexual perpetration. Results revealed a set of shared risk characteristics that predisposed individuals to both sexual coercion and aggression (i.e., belief in rape myths, sexual promiscuity, aggressive tendencies, and empathic deficits). In addition, findings indicated that whether the offenders engaged in only sexual coercion or also used more violent sexually aggressive tactics depended on the presence of two sets of traits unique to these forms of perpetration. Specifically, sexual coercers tended to possess traits that facilitated the use of verbal tactics (i.e., ability to manipulate others and to imagine others' emotional reactions). In contrast, sexual aggressors had characteristics that could increase their willingness to "cross the line" and resort to more violent means to obtain sex from an unwilling partner (i.e., hostility toward women, egocentricity, an impulsive disregard for sociolegal proscriptions, and childhood emotional abuse). A model of general sexual perpetration that directly contrasted sexually coercive and aggressive men was also developed, and hostility toward women was identified as the only predictor capable of predicting perpetrator group membership. Together, these findings suggest that although sexual coercers and aggressors share some underlying risk factors, the etiological patterns of these behaviors are distinct and necessitate individual attention by researchers and prevention programs.

Research has shown that exposure to violent media increases aggression. However, the neural underpinnings of violent-media-related aggression are poorly understood. Additionally, few experiments have tested hypotheses concerning how to reduce violent-media-related aggression. In this experiment, we focused on a brain area involved in the regulation of aggressive impulses-the right ventrolateral prefrontal cortex (rVLPFC). We tested the hypothesis that brain polarization through anodal transcranial direct current stimulation (tDCS) over rVLPFC reduces aggression related to violent video games. Participants (N = 79) were randomly assigned to play a violent or a nonviolent video game while receiving anodal or sham stimulation. Afterward, participants aggressed against an ostensible partner using the Taylor aggression paradigm (Taylor Journal of Personality, 35, 297-310, 1967), which measures both unprovoked and provoked aggression. Among those who received sham stimulation, unprovoked aggression was significantly higher for violent-game players than for nonviolent-game players. Among those who received anodal stimulation, unprovoked aggression did not differ for violent- and nonviolent-game players. Thus, anodal stimulation reduced unprovoked aggression in violent-game players. No significant effects were found for provoked aggression, suggesting tit-for-tat responding. This experiment sheds light on one possible neural underpinning of violent-media-related aggression-the rVLPFC, a brain area involved in regulating negative feelings and aggressive impulses.

2013-01-01

Booster interventions have been presumed to be important methods for maintaining the effects of evidence-based programs for children with behavioral problems, but there has been remarkably little empirical attention to this assumption. The present study examines the effect of a child-oriented booster preventive intervention with children who had previously received an abbreviated version (24 child sessions, 10 parent sessions) of the Coping Power targeted prevention program. Two hundred and forty-one children (152 boys, 89 girls) were screened as having moderate to high levels of aggressive behavior in 4th grade, then half were randomly assigned to receive the abbreviated Coping Power program in 5th grade, and half of the preventive intervention children were then randomly assigned to a Booster condition in 6th grade. The Booster sessions consisted of brief monthly individual contacts, and were primarily with the children. Five assessments across four years were collected from teachers, providing a three-year follow-up for all children who participated in the project. Results indicated that the abbreviated Coping Power program (one-third shorter than the full intervention) had long-term effects in reducing children’s externalizing problem behaviors, proactive and reactive aggression, impulsivity traits and callous-unemotional traits. The Booster intervention did not augment these prevention effects. These findings indicate that a briefer and more readily disseminated form of an evidence-based targeted preventive intervention was effective. The findings have potential implications for policy and guidelines about possible intervention length and booster interventions. PMID:23417235

The link between sensation seeking and aggression: a meta-analytic review.

PubMed

Wilson, Laura C; Scarpa, Angela

2011-01-01

Substantial empirical evidence supports low resting heart rate (HR) as the best replicated psychophysiological correlate of aggression [Ortiz and Raine, 2004]; however, researchers continue to debate the explanatory mechanisms of the phenomenon. Sensation seeking has been proposed as a possible outcome of low resting HR that may lead to aggressive tendencies but findings have been inconsistent in terms of showing a relationship between sensation seeking and aggression. A meta-analysis was conducted on 43 independent effect sizes, from studies with a total of 32,217 participants, to test the hypothesis that sensation seeking would be positively related to aggression across studies. A significant overall effect size was found (d = .1935, P<.001), supporting the hypothesis. Moderator analyses revealed that the relationship differed based on participant and methodological characteristics, such as participant age and the nature of the aggression measurement; however, these conclusions are limited by the uneven number of studies in many of the moderator classes. Overall, the findings provide support for higher levels of aggression in high sensation seekers and have theoretical implications for arousal theory. Further research on the links between arousal, sensation seeking and aggression can inform clinicians about potential interventions. © 2010 Wiley-Liss, Inc.

Moderating effects of autism on parent views of genetic screening for aggression.

PubMed

May, Michael E; Brandt, Rachel C; Bohannan, Joseph K

2012-10-01

Advances in gene-environment interaction research have revealed genes that are associated with aggression. However, little is known about parent perceptions of genetic screening for behavioral symptoms like aggression as opposed to diagnosing disabilities. These perceptions may influence future research endeavors involving genetic linkage studies to behavior, including proactive approaches for parents to avoid events leading to aggression. The purpose of this study was to solicit the perspectives of parents who have children with autism about screening for genes associated with aggression, compared to responses from those who have children without disabilities and those planning to have children. Parents of children with autism were more likely to support screening and the use of the results to seek treatment if necessary. Results are discussed in the context of surveillance screening and systematic early intervention for behavioral symptoms related to autism. The results may provide insight for clincians, researchers, policymakers, and advocacy groups related to diagnosing and treating aggression in people with autism.

Studies into abnormal aggression in humans and rodents: Methodological and translational aspects.

PubMed

Haller, Jozsef

2017-05-01

Here we review the principles based on which aggression is rendered abnormal in humans and laboratory rodents, and comparatively overview the main methodological approaches based on which this behavior is studied in the two categories of subjects. It appears that the discriminating property of abnormal aggression is rule breaking, which renders aggression dysfunctional from the point of view of the perpetrator. We show that rodent models of abnormal aggression were created by the translation of human conditions into rodent equivalents, and discuss how findings obtained with such models may be "translated back" to human conditions when the mechanisms underlying aggression and its possibilities of treatment are investigated. We suggest that the complementary nature of human and rodent research approaches invite a more intense cross-talk between the two sides of aggression research than the one presently observed.

The prevalence of verbal aggression against nurses.

PubMed

McLaughlin, Sue; Gorley, Lyn; Moseley, Laurence

There have been many anecdotal and press reports of verbal aggression against nurses. The authors undertook a structured review of the published literature on the topic. They found that no consistent definitions or time periods had been used, a consistent estimate of prevalence was impossible to establish, studies had been retrospective, and the commonest form of measurement had been self-report. There had been no culmination of replicable knowledge. The claim of most studies is that verbal aggression is commonplace in nursing. The best available evidence suggests that verbal aggression is often viewed as 'part of the job'. Consequences can range from emotional effects such as anger and humiliation, through to intent to leave the profession and for some it may have a negative psychological impact. Further research is needed to investigate the multi-faceted nature of verbal aggression. This must be guided by clear definitions and incorporate standardized measures of the effects of verbal aggression so that nurses can compare findings and fully understand all of the complexities and consequences.

Children's aggressive responses to neutral peer behavior: a form of unprovoked reactive aggression.

PubMed

Kempes, Maaike; Matthys, Walter; de Vries, Han; van Engeland, Herman

2010-04-30

Previous studies that operationalized reactive aggression using behavioral observations in general populations have not taken into account the type of stimulus that elicits reactive aggression. In the present study we define a specific form of reactive aggression, i.e., reactive aggression in response to neutral behavior of a peer, which we will call unprovoked reactive aggression. We were specifically interested in children with severe aggressive behavior problems, since they may respond with reactive aggression even though the opponent did not clearly provoke them, but instead showed neutral behavior. Children with a disruptive behavior disorder (DBD) and normal control (NC) children participated in separate play sessions in which they played with a normal peer (NP). Children with DBD showed more unprovoked reactive aggression than NC children, during a cooperative game. Moreover, for children with DBD, unprovoked reactive aggressive behavior in this game correlated with parent-rated reactive aggression. Results of this study suggest that an unprovoked reactive form of aggression can be identified in children with DBD. Copyright (c) 2008. Published by Elsevier Ireland Ltd.

Physical and psychological aggression in dating relationships of Spanish adolescents: motives and consequences.

PubMed

Fernández-Fuertes, Andres A; Fuertes, Antonio

2010-03-01

The purpose of the study was to examine three aspects of romantic relationships of Spanish adolescents: the prevalence of verbal-emotional and physical aggressive behaviors, correlates of dating violence perpetration (both verbal-emotional and physical aggression), and consequences of violence for victims' well-being. A convenience sample of 567 participants (15-19 years old) who voluntarily completed anonymous, self-report questionnaires was used. All were students from 5 public high schools in Salamanca, Spain. Females reported having perpetrated significantly more aggressive acts in their intimate relationships than males did, although the magnitude of differences between both groups was small; in contrast, no sex differences were noted in the frequency of aggressions suffered by adolescents. A strong relationship was observed between the perpetration and victimization of both verbal-emotional and physical aggression across genders. A strong link was observed between jealousy and aggression perpetration (both verbal-emotional and physical). Finally, verbal-emotional aggression represented the most common form of aggressive behavior used at these ages, and relationship deterioration was the most frequent consequence of arguments. These results demonstrate that the use of abusive behaviors in adolescent dating relationships is prevalent in Spain. Sex differences were evident in the perpetration of aggression, as well as some of the motivations for, and the effects of, dating violence. The present study underlines the need for early intervention programs aimed at decreasing any tolerance for the use of violence in dating relationships of Spanish adolescents. Such programs should include both victimization-based and perpetration-based activities, since the evidence on the relatively mutual nature of dating violence in adolescence points in this direction.

2017-05-01

Dating aggression occurs frequently in early to mid-adolescence and has negative repercussions for psychosocial adjustment and physical health. The patterns of behavior learned during this developmental timeframe may persist in future dating relationships, underscoring the need to identify risk factors for this outcome. The current study examined longitudinal relations between beliefs supporting aggression, anger regulation, and dating aggression. Participants were 176 middle school students in sixth, seventh, and eighth grade (50 % female; 82 % African American). No direct effects were found between beliefs supporting reactive or proactive aggression and dating aggression. Beliefs supporting reactive aggression predicted increased rates of anger dysregulation, and beliefs supporting proactive aggression led to subsequent increases in anger inhibition. Anger dysregulation and inhibition were associated with higher frequencies of dating aggression. An indirect effect was found for the relation between beliefs supporting reactive aggression and dating aggression via anger dysregulation. Another indirect effect emerged for the relation between beliefs supporting proactive aggression and dating aggression through anger inhibition. The study's findings suggested that beliefs supporting proactive and reactive aggression were differentially related to emotion regulation processes, and identified anger dysregulation and inhibition as risk factors for dating aggression among adolescents.

Is there a shared neurobiology between aggression and Internet addiction disorder?

PubMed Central

Hahn, Changtae; Kim, Dai-Jin

2014-01-01

Purpose: Evidences indicate that Internet addiction disorder (IAD) has a higher risk of developing aggression and violent behavior. A few correlation studies between IAD and aggression have implicated a common biological mechanism. However, neurobiological approaches to IAD and aggression have not yet been studied. Methods: A literature search for studies for Internet addiction disorder or aggression was performed in the PubMed database and we selected articles about neurobiology of IAD or aggression. Results: This review includes (a) common neural substrates such as the prefrontal cortex and the limbic system between aggression and IAD; (b) common neuromodulators such as dopamine, norepinephrine, serotonin, opiate and nicotine between aggression and IAD. Conclusions: Through reviewing the relevant literature, we suggested the possibility of common neurobiology between the two psychiatric phenomena and direction of research on aggression in IAD.

The company they keep: drinking group attitudes and male bar aggression.

Dumas, Tara M; Graham, Kathryn; Wells, Samantha

2015-05-01

The purpose of this study was to assess (a) similarities in self-reported bar-aggression-related attitudes and behaviors among members of young male groups recruited on their way to bars and (b) group-level variables associated with individual members' self-reported likelihood of perpetrating physical bar aggression in the past year, controlling for individual attitudes. Young, male, natural drinking groups recruited on their way to a bar district Thursday, Friday, and Saturday nights (n = 167, 53 groups) completed an online survey that measured whether they had perpetrated physical aggression at a bar in the past year and constructs associated with bar aggression, including attitudes toward male bar aggression and frequency of heavy episodic drinking in the past year. Intraclass correlations and chi-square tests demonstrated significant within-group similarity on bar-aggression-related attitudes and behaviors (ps < .01). Hierarchical linear modeling revealed that group attitudes toward bar aggression were significantly associated with individuals' likelihood of perpetrating physical bar aggression, controlling for individual attitudes (p < .01); however, the link between group heavy episodic drinking and self-reported bar aggression was nonsignificant in the full model. This study suggests that the most important group influence on young men's bar aggression is the attitudes of other group members. These attitudes were associated with group members' likelihood of engaging in bar aggression over and above individuals' own attitudes. A better understanding of how group attitudes and behavior affect the behavior of individual group members is needed to inform aggression-prevention programming.

Family Functioning and High Risk Adolescents’ Aggressive Behavior: Examining Effects by Ethnicity

PubMed Central

Varga, Shannon M.; Moudy, Alyssa; Tolan, Patrick H.

2014-01-01

The relationship between family functioning and adolescents’ physical aggression has been well established, but whether these relationships might differ by ethnicity has received less attention. Ethnic variations may be important for targeting prevention programs to specific youth and families. This study examined the longitudinal relationship between family cohesion, parental monitoring, and physical aggression using data from the Multisite Violence Prevention Project sample of high-risk youth (elevated aggression). Participants were 1,232 high-risk middle school students (65% male; 70% African American; 15% Hispanic). Meaningful demographic variations were identified. After controlling for intervention condition and study site, family cohesion was significantly negatively related to physical aggression, more so for Hispanic youth. Parental monitoring was negatively associated with physical aggression for African American youth only. Our findings point to the importance of developing culturally sensitive family interventions to prevent physical aggression in middle school. PMID:25416227

Rejection Sensitivity, Jealousy, and the Relationship to Interpersonal Aggression.

PubMed

Murphy, Anna M; Russell, Gemma

2018-07-01

The development and maintenance of interpersonal relationships lead individuals to risk rejection in the pursuit of acceptance. Some individuals are predisposed to experience a hypersensitivity to rejection that is hypothesized to be related to jealous and aggressive reactions within interpersonal relationships. The current study used convenience sampling to recruit 247 young adults to evaluate the relationship between rejection sensitivity, jealousy, and aggression. A mediation model was used to test three hypotheses: Higher scores of rejection sensitivity would be positively correlated to higher scores of aggression (Hypothesis 1); higher scores of rejection sensitivity would be positively correlated to higher scores of jealousy (Hypothesis 2); jealousy would mediate the relationship between rejection sensitivity and aggression (Hypothesis 3). Study results suggest a tendency for individuals with high rejection sensitivity to experience higher levels of jealousy, and subsequently have a greater propensity for aggression, than individuals with low rejection sensitivity. Future research that substantiates a link between hypersensitivity to rejection, jealousy, and aggression may provide an avenue for prevention, education, or intervention in reducing aggression within interpersonal relationships.

Most educational institutions lack a structured system that provides undergraduate students with research exposure in the medical field. The objective of this paper is to describe the structure of the Medical Research Volunteer Program (MRVP) which was established at the American University of Beirut, Lebanon, as well as to assess the success of the program. The MRVP is a program that targets undergraduate students interested in becoming involved in the medical research field early on in their academic career. It provides students with an active experience and the opportunity to learn from and support physicians, clinical researchers, basic science researchers and other health professionals. Through this program, students are assigned to researchers and become part of a research team where they observe and aid on a volunteer basis. This paper presents the MRVP's four major pillars: the students, the faculty members, the MRVP committee, and the online portal. Moreover, details of the MRVP process are provided. The success of the program was assessed by carrying out analyses using information gathered from the MRVP participants (both students and faculty). Satisfaction with the program was assessed using a set of questions rated on a Likert scale, ranging from 1 (lowest satisfaction) to 5 (highest satisfaction). A total of 211 students applied to the program with a total of 164 matches being completed. Since the beginning of the program, three students have each co-authored a publication in peer-reviewed journals with their respective faculty members. The majority of the students rated the program positively. Of the total number of students who completed the program period, 35.1 % rated the effectiveness of the program with a 5, 54.8 % rated 4, and 8.6 % rated 3. A small number of students gave lower ratings of 2 and 1 (1.1 % and 0.4 %, respectively). The MRVP is a program that provides undergraduate students with the opportunity to learn about research firsthand

Apparent Motives for Aggression in the Social Context of the Bar

Objective Little systematic research has focused on motivations for aggression and most of the existing research is qualitative and atheoretical. This study increases existing knowledge by using the theory of coercive actions to quantify the apparent motives of individuals involved in barroom aggression. Objectives were to examine: gender differences in the use of compliance, grievance, social identity, and excitement motives; how motives change during an aggressive encounter; and the relationship of motives to aggression severity. Method We analyzed 844 narrative descriptions of aggressive incidents observed in large late-night drinking venues as part of the Safer Bars evaluation. Trained coders rated each type of motive for the 1,507 bar patrons who engaged in aggressive acts. Results Women were more likely to be motivated by compliance and grievance, many in relation to unwanted sexual overtures from men; whereas men were more likely to be motivated by social identity concerns and excitement. Aggressive acts that escalated tended to be motivated by identity or grievance, with identity motivation especially associated with more severe aggression. Conclusions A key factor in preventing serious aggression is to develop approaches that focus on addressing identity concerns in the escalation of aggression and defusing incidents involving grievance and identity motives before they escalate. In bars, this might include training staff to recognize and defuse identity motives and eliminating grievance-provoking situations such as crowd bottlenecks and poorly managed queues. Preventive interventions generally need to more directly address the role of identity motives, especially among men. PMID:24224117

Demolishing the competition: the longitudinal link between competitive video games, competitive gambling, and aggression.

PubMed

Adachi, Paul J C; Willoughby, Teena

2013-07-01

The majority of research on the link between video games and aggression has focused on the violent content in games. In contrast, recent experimental research suggests that it is video game competition, not violence, that has the greatest effect on aggression in the short-term. However, no researchers have examined the long-term relationship between video game competition and aggression. In addition, if competition in video games is a significant reason for the link between video game play and aggression, then other competitive activities, such as competitive gambling, also may predict aggression over time. In the current study, we directly assessed the socialization (competitive video game play and competitive gambling predicts aggression over time) versus selection hypotheses (aggression predicts competitive video game play and competitive gambling over time). Adolescents (N = 1,492, 50.8 % female) were surveyed annually from Grade 9 to Grade 12 about their video game play, gambling, and aggressive behaviors. Greater competitive video game play and competitive gambling predicted higher levels of aggression over time, after controlling for previous levels of aggression, supporting the socialization hypothesis. The selection hypothesis also was supported, as aggression predicted greater competitive video game play and competitive gambling over time, after controlling for previous competitive video game play and competitive gambling. Our findings, taken together with the fact that millions of adolescents play competitive video games every day and that competitive gambling may increase as adolescents transition into adulthood, highlight the need for a greater understanding of the relationship between competition and aggression.

Deconstructing Hegemonic Masculinity: The Roles of Antifemininity, Subordination to Women, and Sexual Dominance in Men’s Perpetration of Sexual Aggression

PubMed Central

Smith, Rachel M.; Parrott, Dominic J.; Swartout, Kevin M.; Tharp, Andra Teten

2018-01-01

The aim of this investigation was to examine a theoretically based mechanism by which men’s adherence to antifeminine norms is associated with their perpetration of sexual aggression toward intimate partners. Participants were 208 heterosexual men between the ages of 21–35 who had consumed alcohol in the past year. They were recruited from a large southeastern United States city. Participants completed self-report measures of hegemonic masculinity (i.e., antifemininity, sexual dominance), masculine gender role stress, and sexual aggression toward an intimate partner during the past 12 months. Results indicated that adherence to the antifemininity norm and the tendency to experience stress when in subordinate positions to women were indirectly related to sexual aggression perpetration via adherence to the sexual dominance norm. Thus, the men who adhere strongly to these particular hegemonic masculine norms may feel compelled to be sexually aggressive and/or coercive toward an intimate partner in order to maintain their need for dominance within their intimate relationship. Implications for future research and sexual aggression prevention programming are discussed.

Exogenous Testosterone Rapidly Increases Aggressive Behavior in Dominant and Impulsive Men.

2017-08-15

Although traditional wisdom suggests that baseline levels of testosterone (T) promote aggressive behavior, decades of research have produced findings that have been largely weak and inconsistent. However, more recent experimental work suggests that exogenous administration of T rapidly potentiates amygdala and hypothalamus responses to angry facial expressions. Notably, these brain regions are rich in androgen receptors and play a key role in modulating aggressive behavior in animal models. The present experiment extends this work by examining whether acutely increasing T potentiates aggressive behavior in men. In a double-blind, placebo-controlled, between-subject design, healthy adult men (n = 121) were administered either T or placebo, and subsequently engaged in a well-validated decision-making game that measures aggressive behavior in response to social provocation. In light of prior correlational research, we also assessed the extent to which T's effects on aggressive behavior would depend on variability in trait dominance and/or trait self-control. Exogenous T on its own did not modulate aggressive behavior. However, T's effects on aggression were strongly influenced by variation in trait dominance and trait self-control. Specifically, T caused an increase in aggressive behavior, but only among men scoring relatively high in trait dominance or low in trait self-control. These findings are the first to demonstrate that T can rapidly (within 60 minutes) potentiate aggressive behavior, but only among men with dominant or impulsive personality styles.

2013-01-01

To explore the relationships between verbal aggression, physical aggression and inappropriate sexual behaviour following acquired brain injury. Multivariate statistical modelling of observed verbal aggression, physical aggression and inappropriate sexual behaviour utilizing demographic, pre-morbid, injury-related and neurocognitive predictors. Clinical records of 152 participants with acquired brain injury were reviewed, providing an important data set as disordered behaviours had been recorded at the time of occurrence with the Brain Injury Rehabilitation Trust (BIRT) Aggression Rating Scale and complementary measures of inappropriate sexual behaviour. Three behavioural components (verbal aggression, physical aggression and inappropriate sexual behaviour) were identified and subjected to separate logistical regression modelling in a sub-set of 77 participants. Successful modelling was achieved for both verbal and physical aggression (correctly classifying 74% and 65% of participants, respectively), with use of psychotropic medication and poorer verbal function increasing the odds of aggression occurring. Pre-morbid history of aggression predicted verbal but not physical aggression. No variables predicted inappropriate sexual behaviour. Verbal aggression, physical aggression and inappropriate sexual behaviour following acquired brain injury appear to reflect separate clinical phenomena rather than general behavioural dysregulation. Clinical markers that indicate an increased risk of post-injury aggression were not related to inappropriate sexual behaviour.

We tested the hypotheses that the Fast Track intervention program for high-risk children would reduce adult aggressive behavior and that this effect would be mediated by decreased testosterone responses to social provocation. Participants were a subsample of males from the full trial sample, who during kindergarten had been randomly assigned to the 10-year Fast Track intervention or to a control group. The Fast Track program attempted to develop children's social competencies through child social-cognitive and emotional-coping skills training, peer-relations coaching, academic tutoring, and classroom management, as well as training for parents to manage their child's behavior. At a mean age of 26 years, participants responded to laboratory provocations. Results indicated that, relative to control participants, men assigned to the intervention demonstrated reduced aggression and testosterone reactivity to social provocations. Moreover, reduced testosterone reactivity mediated the effect of intervention on aggressive behavior, which provides evidence for an enduring biological mechanism underlying the effect of early psychosocial intervention on aggressive behavior in adulthood.

The psychobiology of aggression and violence: bioethical implications.

PubMed

Díaz, José Luis

2010-01-01

Bioethics is concerned with the moral aspects of biology and medicine. The bioethical relevance of aggression and violence is clear, as very different moral and legal responsibilities may apply depending on whether aggression and violence are forms of behaviour that are innate or acquired, deliberate or automatic or not, or understandable and justifiable based on causes. Biological research and natural science theories are a basic ingredient for reflections, arguments and decisions on such matters. This study presents the problem of the causes of aggressive behaviour, the evolutionary understanding and definition of aggressive behaviour, the biological basis for this behaviour and the link between emotions and aggression. A growing body of evidence suggests that innate factors of behaviour (be they genetic or neurobiological) do not by themselves define behaviour and nor do acquired factors such as learning, cultural norms or worldviews. Both types of factor interact from the outset to shape a development process that mutually interacts to define beliefs or behaviour.

2007-01-01

This study extends the use of the Impulsive/Premeditated Aggression Scale for subtyping aggressive behavior among adolescents with Conduct Disorder. Of the Conduct Disorder symptoms, aggression has the strongest prognostic and treatment implications. While aggression is a complex construct, convergent evidence supports a dichotomy of impulsive and premeditated aggressive subtypes that are qualitatively different from one another in terms of phenomenology and neurobiology. Previous attempts at measuring subtypes of aggression in children and adults are not clearly generalizable to adolescents. Sixty-six adolescents completed a questionnaire for characterizing aggression (Impulsive/Premeditated Aggression Scale), along with standard measures of personality and general functioning. Principal components analysis demonstrated two stable factors of aggression with good internal consistency and construct validity. Compared to the premeditated aggression factor, the impulsive aggression factor was associated with a broader range of personality, thought, emotional, and social problems. As in the adult and child literature, characterization of aggressive behavior into two subtypes appears to be relevant to understanding individual differences among adolescents with Conduct Disorder.

2017-03-01

In this study, we compared three groups of women admitted to a public forensic inpatient facility over the course of a two-year period. Detailed and systematic examination of social and psychiatric histories revealed that the group with the most persistent levels of aggression differed from the other two groups with respect to frequency of self-harming behavior, intellectual impairment, hypothyroidism, a childhood diagnosis of attention deficit-hyperactivity disorder (ADHD), and age of onset of psychiatric and behavioral symptoms. The high-aggression group also had the highest rate of childhood physical and sexual abuse, but the difference between that group and the two lower aggression groups did not achieve statistical significance. From the standpoint of childhood adversity, 94 percent of those in the high-aggression group had been placed outside of the original home by age 11. Eighty-nine percent were intellectually impaired. At admission, physical examinations revealed that 50 percent had a history of hypothyroidism and two-thirds were obese. Before admission, most had manifested severe aggression and emotional dysregulation, as evinced by high levels of self-harm, suicide attempts, and aggressive behavior in previous institutional settings that was both frequent and intense. Patients who share these characteristics are currently placed on a ward at the hospital with a milieu and individual therapy programs that are based on a dialectical behavior therapy approach that targets key symptoms of emotional and behavioral dysregulation. © 2017 American Academy of Psychiatry and the Law.

Perceived marginalization and aggression: a longitudinal study with low-educated adolescents.

PubMed

Issmer, Christian; Wagner, Ulrich

2015-03-01

Social exclusion can evoke aggression. In the past two decades research has demonstrated this effect both for interpersonal and societal forms of exclusion. In addition, recent violent uprisings, like the London riots in August 2011, have been linked to social exclusion in the media. However, so far there is a lack of longitudinal studies which examine the aggression-enhancing effect of societal-level exclusion (i.e., marginalization) in disadvantaged groups. This research investigates the impact of perceived marginalization on aggression in a sample of N = 181 adolescents with a low educational background by means of a two-wave longitudinal study. The results of structural equation analyses are consistent with the hypothesis that perceived marginalization enhances aggression, and that this effect is mediated by the extent of negative societal meta-stereotypes. Furthermore, the reverse path from aggression to perceptions of marginalization is also significant. We discuss the implications of these findings and highlight practical consequences. © 2014 The British Psychological Society.

Patient aggression is a longstanding problem in general hospital nursing. Staff training is recommended to tackle workplace aggression originating from patients or visitors, yet evidence on training effects is scarce. To review and collate current research evidence on the effect of aggression management training for nurses and nursing students working in general hospitals, and to derive recommendations for further research. Systematic, narrative review. Embase, MEDLINE, the Cochrane library, CINAHL, PsycINFO, pubmed, psycArticles, Psychology and Behavioural Sciences Collection were searched for articles evaluating training programs for staff and students in acute hospital adult nursing in a 'before/after' design. Studies published between January 2000 and September 2011 in English, French or German were eligible of inclusion. The methodological quality of included studies was assessed with the 'Quality Assessment Tool for Quantitative Studies'. Main outcomes i.e. attitudes, confidence, skills and knowledge were collated. Nine studies were included. Two had a weak, six a moderate, and one a strong study design. All studies reported increased confidence, improved attitude, skills, and knowledge about risk factors post training. There was no significant change in incidence of patient aggression. Our findings corroborate findings of reviews on training in mental health care, which point to a lack of high quality research. Training does not reduce the incidence of aggressive acts. Aggression needs to be tackled at an organizational level. Copyright © 2014 Elsevier Ltd. All rights reserved.

Incontinence--an aggressive approach to treatment: a case series.

Dornan, P R

2005-12-01

Recent evidence suggests that, for some, leaking urine may be a barrier to physical activity. Although important from a lifestyle point of view, bladder problems and incontinence also affect both men and women socially, psychologically and economically. For example, it can be particularly distressing when incontinence occurs post-prostate surgery, especially if these patients were continent before surgery. This case series outlines an aggressive, innovative, exercise-based approach to the management of stress incontinence post-prostatectomy. The program attempts to enhance neuromuscular and vascular systems associated with continence, with emphasis placed on the abdominal and pelvic floor muscles. The program was undertaken by 14 incontinent post-prostatectomy patients (mean age 63.5 y, using a mean of 3.5 sanitary pads per day). The program was initiated a mean of two months post-op and had a mean duration of six months. Upon completion of the program. 10 patients were found to be completely dry with three retaining a small leakage (a few drops). The 14th could not comply with the program because of illness. The results of this study appear promising in this patient population. There are indications for further research.

A Moderator Model of Alcohol Use and Dating Aggression among Young Adults.

PubMed

Collibee, Charlene; Furman, Wyndol

2018-03-01

Dating aggression has been identified as a priority public health concern. Although alcohol use is a known robust risk factor for dating aggression involvement, such usage is neither necessary nor sufficient for dating aggression involvement. As such, a growing topic of interest is a better understanding of when, and for whom, alcohol use increases risk. A theoretical moderator model posits that associations between alcohol use and dating aggression involvement vary depending on both background (e.g., psychopathology) and situational (e.g., relationship characteristics) risk factors. Alcohol use is thought to be more strongly associated with dating aggression in the context of these other risk factors. Using an intensive longitudinal design, we collected six waves of data spanning 6 months from 120 participants (60 females; M age W1 = 22.44). Alcohol use and relationship risk were both associated with increases in dating aggression involvement. Consistent with a moderator model, interactions emerged between alcohol use and relationship risk for subsequent dating aggression involvement. The findings underscore the importance of alcohol use and relationship risk for the development of intervention and prevention programs.

Patterns of Change in Adolescent Dating Victimization and Aggression During Middle School.

2018-03-01

Although mounting evidence suggests dating victimization and aggression begin in early adolescence, little work has examined the pattern of these behaviors across this age. This longitudinal study examined trajectories of dating victimization and aggression across middle school using 12 waves of data. A sample of early adolescents (N = 1369, 52.3% girls; 83% African American; 15% Hispanic or Latino) residing in an urban, economically disadvantaged area participated in this study. Youth completed measures of dating victimization and aggression quarterly across the 3 years of middle school. Although results indicated a general trend of increasing dating victimization and aggression across middle school, variation existed for boys and girls. Specifically, girls showed increasing patterns of both, whereas boys remained relatively stable across time. Dating victimization and aggression were also highly correlated across time. These findings support the implementation and refinement of prevention programming aimed at preventing and reducing dating aggression and victimization in middle school.

Urban ethnic minority youth are often exposed to high levels of aggression and violence. As such, many aggression intervention programs that have been designed with suburban nonethnic minority youth have been used or slightly adapted in order to try and meet the needs of high-risk urban youth. The current study contributes to the literature base by examining how well a range of social-cognitive, emotional distress and victimization, and prosocial factors are related to youth aggression in a sample of urban youth. This study utilized data gathered from 109 9- to 15-year-old youth (36.7% male; 84.4% African American) and their parents or caregivers. A series of hierarchical multiple regressions were fit predicting youth aggression from social-cognitive variables, victimization and distress, and prosocial variables, controlling for youth gender and age. Each set of variables explained a significant and unique amount of the variance in youth aggressive behavior. The full model including all predictors accounted for 41% of the variance in aggression. Models suggest that youth with stronger beliefs supportive of violence, youth who experience more overt victimization, and youth who experience greater distress in overtly aggressive situations are likely to be more aggressive. In contrast, youth with higher self-esteem and youth who endorse greater leadership efficacy are likely to be less aggressive. Contrary to hypotheses, hostile attributional bias and knowledge of social information processing, experience of relational victimization, distress in relationally aggressive situations, and community engagement were not associated with aggression. Our study is one of the first to address these important questions for low-income, predominately ethnic minority urban youth, and it has clear implications for adapting aggression prevention programs to be culturally sensitive for urban African American youth.

The displaced aggression questionnaire.

Previous measures of aggressive personality have focused on direct aggression (i.e., retaliation toward the provoking agent). An original self-report measure of trait displaced aggression is presented. Exploratory and confirmatory factor analyses provided support for a 3-factor conceptualization of the construct. These analyses identified an affective dimension (angry rumination), a cognitive dimension (revenge planning), and a behavioral dimension (general tendency to engage in displaced aggression). The trait measure demonstrated good internal consistency and test-retest reliability as well as convergent and discriminant construct validity. Unlike other related personality measures, trait displaced aggression significantly predicted indirect indicators of real-world displaced aggression (i.e., self-reported domestic abuse and road rage) as well as laboratory displaced aggression in 2 experiments.

Aggression is a universal social behavior important for the acquisition of food, mates, territory, and social status. Aggression in Drosophila is context-dependent and can thus be expected to involve inputs from multiple sensory modalities. Here, we use mechanical disruption and genetic approaches in Drosophila melanogaster to identify hearing as an important sensory modality in the context of intermale aggressive behavior. We demonstrate that neuronal silencing and targeted knockdown of hearing genes in the fly's auditory organ elicit abnormal aggression. Further, we show that exposure to courtship or aggression song has opposite effects on aggression. Our data define the importance of hearing in the control of Drosophila intermale aggression and open perspectives to decipher how hearing and other sensory modalities are integrated at the neural circuit level.

Social goals are associated with behaviors and adjustment among peers. However, it remains unclear whether goals predict adolescent social development. We examined prospective associations among goals, physical and relational aggression, social preference, and popularity during middle school (N = 384 participants, ages 12-14 years). Agentic (status, power) goals predicted increased relational aggression and communal (closeness) goals predicted decreased physical aggression. Popularity predicted increases and preference predicted decreases in both forms of aggression. Goals moderated longitudinal links between aggression and popularity: Aggression predicted increases in popularity and vice versa for youth with higher agentic goals, and popularity predicted increases in physical aggression for youth with higher agentic and lower communal goals. Implications for research on social goals, aggression, and popularity are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

The theory of planned behavior, materialism, and aggressive driving.

Efrat, Kalanit; Shoham, Aviv

2013-10-01

Aggressive driving is a growing problem worldwide. Previous research has provided us with some insights into the characteristics of drivers prone to aggressiveness on the road and into the external conditions triggering such behavior. Little is known, however, about the personality traits of aggressive drivers. The present study proposes planned behavior and materialism as predictors of aggressive driving behavior. Data was gathered using a questionnaire-based survey of 220 individuals from twelve large industrial organizations in Israel. Our hypotheses were tested using structural equation modeling. Our results indicate that while planned behavior is a good predictor of the intention to behave aggressively, it has no impact on the tendency to behave aggressively. Materialism, however, was found to be a significant indicator of aggressive driving behavior. Our study is based on a self-reported survey, therefore might suffer from several issues concerning the willingness to answer truthfully. Furthermore, the sampling group might be seen as somewhat biased due to the relatively high income/education levels of the respondents. While both issues, aggressive driving and the theory of planned behavior, have been studied previously, the linkage between the two as well as the ability of materialism to predict aggressive behavior received little attention previously. The present study encompasses these constructs providing new insights into the linkage between them. Copyright © 2013 Elsevier Ltd. All rights reserved.

[Comparison of the factors influencing young adolescents' aggression according to family structure].

Yun, Eun Kyoung; Shin, Sung Hee

2013-06-01

This cross-sectional study was done to compare factors influencing young adolescents' aggression according to family structure. Participants were 680 young adolescents aged 11 to 15 years (113 in single father families, 136 in single mother families, 49 in grandparent families, and 382 in both-parent families). All measures were self-administered. Data were analyzed using SPSS 18.0 program and factors affecting young adolescents' aggression were analyzed by stepwise multiple regression. Levels of young adolescents' aggression and all variables were significantly different among the four family structure groups. Factors influencing young adolescents' aggression were also different according to these 4 groups. For single father families, depression-anxiety and family hardiness significantly predicted the level of young adolescents' aggression (adjusted R square=.37, p<.001). For single mother families, depression-anxiety, gender, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For grandparent families, depression-anxiety and family support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For both-parent families, depression-anxiety, family hardiness, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.48, p<.001). Nurses working with young adolescents should consider family structure-specific factors influencing aggression in this population.

In Singapore, anecdotal evidence suggests that nurses are concerned about managing aggressive incidents in the emergency department. In this study, registered nurses' perceptions of managing aggressive patients in an emergency department were explored. Ten registered nurses from the emergency department of an acute public hospital in Singapore were interviewed. Four overarching themes emerged from the thematic analysis: (i) impact of aggressive patients on nurses; (ii) nursing assessment of aggressive behaviors; (iii) nursing management of aggressive behaviors; and (iv) organizational support and responsiveness. Further research is required to better support nurses to deliver optimal care for aggressive patients and achieve positive and effective outcomes. © 2015 Wiley Publishing Asia Pty Ltd.

Predictors of child-to-parent aggression: A 3-year longitudinal study.

PubMed

Calvete, Esther; Orue, Izaskun; Gamez-Guadix, Manuel; Bushman, Brad J

2015-05-01

Although we rarely hear about it, children sometimes aggress against their parents. This is a difficult topic to study because abused parents and abusive children are both reluctant to admit the occurrence of child-to-parent aggression. There are very few research studies on this topic, and even fewer theoretical explanations of why it occurs. We predicted that exposure to violence in the home (e.g., parents aggressing against each other) and ineffective parenting (i.e., parenting that is overly permissive or lacks warmth) influences cognitive schemas of how children perceive themselves and the world around them (i.e., whether aggression is normal, whether they develop grandiose self-views, and whether they feel disconnected and rejected), which, in turn, predicts child-to-parent aggression. In a 3-year longitudinal study of 591 adolescents and their parents, we found that exposure to violence in Year 1 predicted child-to-parent aggression in Year 3. In addition, parenting characterized by lack of warmth in Year 1 was related to narcissistic and entitled self-views and disconnection and rejection schemas in Year 2, which, in turn, predicted child-to-mother and child-to-father aggression in Year 3. Gender comparisons indicated that narcissism predicted child-to-parent aggression only in boys and that exposure to violence was a stronger predictor of child-to-father violence in boys. This longitudinal study increases our understanding of the understudied but important topic of child-to-parent aggression, and will hopefully stimulate future research.

In the article, the name of author Edward Deci was missing his middle name initial and should have read as Edward L. Deci. In addition, an incorrect version of figure 1 was published.] Recent studies have examined whether electronic games foster aggression. At present, the extent to which games contribute to aggression and the mechanisms through which such links may exist are hotly debated points. In current research we tested a motivational hypothesis derived from self-determination theory-that gaming would be associated with indicators of human aggression to the degree that the interactive elements of games serve to impede players' fundamental psychological need for competence. Seven studies, using multiple methods to manipulate player competence and a range of approaches for evaluating aggression, indicated that competence-impeding play led to higher levels of aggressive feelings, easier access to aggressive thoughts, and a greater likelihood of enacting aggressive behavior. Results indicated that player perceived competence was positively related to gaming motivation, a factor that was, in turn, negatively associated with player aggression. Overall, this pattern of effects was found to be independent of the presence or absence of violent game contents. We discuss the results in respect to research focused on psychological need frustration and satisfaction and as they regard gaming-related aggression literature.

Culotta, Carmen M; Goldstein, Sara E

2008-03-01

The authors examined how relational aggression, physical aggression, and proactive prosocial behavior were associated with jealousy and social anxiety in a diverse sample of 60 middle school students. After the authors controlled for gender and race, jealousy predicted relational aggression and proactive prosocial behavior, but it did not predict physical aggression. Additionally, social anxiety predicted proactive prosocial behavior. Adolescents who were more jealous in their peer relationships also tended to engage in relational aggression and proactive prosocial behavior, and adolescents who were more socially anxious also tended to be proactively prosocial. The authors discuss the implications of these findings and suggest directions for future research.

Life Course Associations between Victimization and Aggression: Distinct and Cumulative Contributions

2014-01-01

The connections between early maltreatment and later aggression are well established in the literature, however gaps remain in our understanding of developmental processes. This study investigates the cascading lifecourse linkages between victimization experiences from childhood through early adulthood andlater aggressive behavior. The diverse, at-risk sample is of particular importance to child and adolescent specialists, as it represents highly vulnerable youth accessible through conventional school settings. In addition to direct pathways from proximal life periods, path analysis revealed significant indirect mediated pathways through which earlier life victimizationcontributes to aggressive behaviors in later life periods as well as revictimization. Multivariateregressions support theorized cumulative effects of multi-form victimization as well as distinct contributions of victimization domains (emotional, witnessing, physical, property, and sexual) in explaining aggressive behavior.Consistent with theorizing about the developmental impact of early maltreatment, results bolster the importance of interrupting pathways from victimization to revictimization and later aggression. Findings are evaluated in light of implications for early identification and prevention programming. PMID:26190899

Workplace victimization: aggression from the target's perspective.

Aquino, Karl; Thau, Stefan

2009-01-01

This article reviews research on workplace victimization, which we define as acts of aggression perpetrated by one or more members of an organization that cause psychological, emotional, or physical harm to their intended target. We compare several types of victimizing behaviors that have been introduced into the organizational psychology literature to illustrate differences and similarities among them. We then review studies looking at who is likely to become a victim of aggression. Predictors include personality, demographic, behavioral, structural, and organizational variables. We also review research on coping strategies for victimization, which include problem-focused and emotion-focused strategies. We conclude with a summary of challenges for victimization research. These include addressing the proliferation of constructs and terms into the literature, attempting to clarify inconclusive findings, and using theory to guide the selection of study variables.

This research tested the association between the Dark Triad and driving aggression as well as the incremental validity of the Dark Triad in predicting aggressive driving and the mediation role of the Dark Triad in the relationship between Big Five personality factors and aggressive driving. 274 undergraduate students in Study 1 and 95 amateur drivers in Study 2 completed measures of the Dark Triad (Machiavellianism, Narcissism and Psychopathy), the Big Five personality factors and the aggressive driving expression. Results showed that all the Dark Triad traits were related to aggressive driving behavior in both Study 1 and Study 2 and that the Dark Triad predicted driving aggression after the effect of the Big five personality factors was controlled, with Psychopathy being the strongest predictor of driving aggression in both Study 1 and Study 2. Machiavellianism and Psychopathy mediated the relationship between Emotional Stability, Agreeableness, Conscientiousness on one hand and aggressive driving on the other hand.

Psychopathy and instrumental aggression: Evolutionary, neurobiological, and legal perspectives.

PubMed

Glenn, Andrea L; Raine, Adrian

2009-01-01

In the study of aggression, psychopathy represents a disorder that is of particular interest because it often involves aggression which is premeditated, emotionless, and instrumental in nature; this is especially true for more serious types of offenses. Such instrumental aggression is aimed at achieving a goal (e.g., to obtain resources such as money, or to gain status). Unlike the primarily reactive aggression observed in other disorders, psychopaths appear to engage in aggressive acts for the purpose of benefiting themselves. This is especially interesting in light of arguments that psychopathy may represent an alternative life-history strategy that is evolutionarily adaptive; behaviors such as aggression, risk-taking, manipulation, and promiscuous sexual behavior observed in psychopathy may be means by which psychopaths gain advantage over others. Recent neurobiological research supports the idea that abnormalities in brain regions key to emotion and morality may allow psychopaths to pursue such a strategy-psychopaths may not experience the social emotions such as empathy, guilt, and remorse that typically discourage instrumentally aggressive acts, and may even experience pleasure when committing these acts. Findings from brain imaging studies of psychopaths may have important implications for the law.

Parenting styles and bullying. The mediating role of parental psychological aggression and physical punishment.

PubMed

Gómez-Ortiz, Olga; Romera, Eva María; Ortega-Ruiz, Rosario

2016-01-01

Studies concerning parenting styles and disciplinary practices have shown a relationship between both factors and bullying involvement in adolescence. The scarce available evidence suggests that abusive disciplinary practices increase teenagers' vulnerability to abuse in school or the likelihood of them becoming abusers of their peers in the same context. However, there is a lack of knowledge about the indirect effect of parenting styles in adolescents' bullying involvement through disciplinary practices, although a relationship between parenting styles and disciplinary practices has been shown. The aim of this research was to determine the mediating role of punitive parental discipline (physical punishment and psychological aggression) between the dimensions of parents' parenting styles and their children's involvement in bullying victimization and aggression. We used a sample comprising 2060 Spanish high school students (47.9% girls; mean age=14.34). Structural equation modeling was performed to analyze the data. The results confirmed the mediating role of parental discipline between the parenting practices analyzed and students' aggression and victimization. Significant gender-related differences were found for aggression involvement, where boys were for the most part linked to psychological aggression disciplinary practices and girls to physical punishment. Victimization directly correlated with parental psychological aggression discipline behavior across both sexes. In conclusion, the results seem to suggest that non-democratic parenting styles favor the use of punitive discipline, which increases the risk of adolescents' bullying involvement. Therefore, intervention programs must involve parents to make them aware about the important role they play in this process and to improve their parenting styles. Crown Copyright © 2015.

Family influences on the development of aggression and violence.

PubMed

Labella, Madelyn H; Masten, Ann S

2018-02-01

Recent research confirms that many of the most salient risk and protective factors for the development of aggression and violence reside in the family system. Family-based risks begin before birth, encompassing genetic and epigenetic processes. Contextual stressors (e.g., poverty, conflict) may impact development directly or indirectly through disrupted parenting behavior, including high negativity, low warmth, harshness, and exposure to violence. The family can also serve as a powerful adaptive system counteracting the risk of aggression and violence. Parents can promote healthy behavioral development through warmth, structure, and prosocial values, as well as by fostering adaptive resources in the child and community. Successful interventions often reduce aggression and violence by supporting parents and families. Recent insights and future directions for research and practice are discussed. Copyright © 2017.

Positively Biased Self-Perceptions of Peer Acceptance and Subtypes of Aggression in Children

Lynch, Rebecca J.; Kistner, Janet A.; Stephens, Haley F.; David-Ferdon, Corinne

2016-01-01

There is a growing body of research linking children’s positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the “disputed overestimation hypothesis,” which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children’s peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications. PMID:26423823

Community research has been an integral and influential component of the National Research Program since the late 1970s. Institutionalization of community research in the Community Clinical Oncology Program (CCOP) has resulted in successful collaborations, meaningful accrual, achievement of quality standards, and translation of research into clinical practice. Although the national clinical trial system is undergoing modernization and improvement, the success of the CCOP and minority-based CCOP in cancer treatment, prevention, and control research is being extended to include cancer care delivery research in the newly created National Cancer Institute (NCI) Community Oncology Research Program. This article briefly presents a historic perspective of community involvement in federally sponsored clinical trials and introduces the continued involvement in the newly created NCI program.

Nursing and aggression in the workplace: a systematic review.

PubMed

Edward, Karen-leigh; Ousey, Karen; Warelow, Philip; Lui, Steve

Personal experiences of aggression or violence in the workplace lead to serious consequences for nurses, their patients, patient care and the organisation as a whole. While there is a plethora of research on this topic, no review is available that identifies types of aggression encountered, individuals perceived to be most at risk and coping strategies for victims. The aim of this systematic review was to examine occupational anxiety related to actual aggression in the workplace for nurses. Databases (MEDLINE, CINAHL and PsycINFO) were searched, resulting in 1543 titles and abstracts. After removal of duplicates and non-relevant titles, 137 papers were read in full. Physical aggression was found to be most frequent in mental health, nursing homes and emergency departments while verbal aggression was more commonly experienced by general nurses. Nurses exposed to verbal or physical abuse often experienced a negative psychological impact post incident.

Unintentional Misreporting on Self-Report Measures of Sexually Aggressive Behavior: An Interview Study.

The development of effective sexual aggression prevention programs for men relies on data garnered from studies using self-report measures of sexual aggression perpetration. However, few studies have focused on understanding and improving self-report measures of sexual aggression perpetration. The current study used open-ended interviews to explore the nature and frequency of community men's (N = 34) unintentional misreporting-including both overreporting and underreporting-on two self-report measures of sexual aggression perpetration: the Sexual Experiences Survey-Long Form Perpetration (SES-LFP; Koss et al., 2007) and the Sexual Strategies Scale (SSS; Strang, Peterson, Hill, & Heiman, 2013a). Item misinterpretation led to both overreporting and underreporting of sexual aggression, although underreporting was more common. Men's interpretations of items, decision-making processes, and reasons for producing discrepant reports across measures were analyzed and discussed. Results could help inform efforts to refine self-report measurement of men's sexual aggression.

Impulsive versus premeditated aggression: implications for mens rea decisions.

PubMed

Barratt, Ernest S; Felthous, Alan R

2003-01-01

Science can provide more information about the nature of aggressive acts, and therefore the mens rea of criminal offenses, than is commonly assumed. For example, progress has been made in classifying aggression as impulsive or premeditated within the context of the role of conscious experience in controlling behavior. This review of the status of the scientific ability to distinguish conscious from unconscious acts and more specifically impulsive from premeditated aggressive acts is organized around four themes: (i) How is aggression defined and measured in general? (ii) How does the distinction between impulsive and premeditated aggression relate to the legal concept of mens rea? (iii) How do various scientific disciplines contribute to the mind/body discourse? (iv) What risk factors are associated with impulsive and premeditated aggression respectively? The authors conclude that the most promising approach to researching the nature of behavioral intention and motivation is to apply a discipline neutral model that integrates the data from multiple disciplines, collectively designated the cognitive neurosciences.

Neuroendocrine aspects of pediatric aggression: Can hormone measures be clinically useful?

PubMed Central

Barzman, Drew H; Patel, Avni; Sonnier, Loretta; Strawn, Jeffrey R

2010-01-01

Pediatric aggression is common in human societies, mainly presenting as impulsive aggression or predatory aggression. Numerous psychiatric disorders can contain aggression as a symptom, leading to difficulties in diagnosis and treatment. This review focuses on the biological systems that affect pediatric aggression. We review the hypothalamic–pituitary–adrenal (HPA) axis, the hypothalamic–pituitary–gonadal (HPG) axis, and the mechanisms by which these axes influence the body and mind of aggressive children and adolescents. Although this review focuses on the HPA and HPG axes, it is important to note that other biological systems have relationships with these two axes. Based on the results of the studies reviewed, elevated cortisol concentrations were associated with impulsive aggression, whereas, low levels of cortisol were associated with callous-unemotional traits similar to predatory aggression. Higher levels of dehydroepiandrosterone were correlated with higher levels of aggression as were higher levels of testosterone. However, there have been discrepancies in the results between various studies, indicating the need for more research on hormonal levels and pediatric aggression. In the future, hormonal levels may be useful in determining what treatments will work best for certain pediatric patients. PMID:21127686

Entitled vengeance: A meta-analysis relating narcissism to provoked aggression.

PubMed

Rasmussen, Kyler

2016-07-01

Narcissism has long been used to predict aggressive or vengeful responses to provocations from others. The strength of this relation can, however, vary widely from study to study. Narcissism and revenge were examined in 84 independent samples (N = 11297), along with the moderating role of sample type (i.e., child/adolescent, prisoner, undergraduate, or general samples), type of narcissism measure used (i.e., Narcissistic Personality Inventory, Psychological Entitlement Scale, Short D3, etc.), the nature of the provocation, and the type of provoked aggression examined. Narcissism was positively related to provoked aggression across studies (ρ = .25), but that relation was stronger in child/adolescent samples (ρ = .36) and when measures of entitlement or vulnerable narcissism were employed (ρ = .29). Implications for practical research, as well as neglected areas of research on narcissism and provoked aggression are discussed. Aggr.

Reyes, H. Luz McNaughton; Foshee, Vangie A.; Bauer, Daniel J.; Ennett, Susan T.

2012-01-01

While numerous studies have established a link between alcohol use and partner violence in adulthood, little research has examined this relation during adolescence. The current study used multivariate growth models to examine relations between alcohol use and dating aggression across grades 8 through 12 controlling for shared risk factors (common causes) that predict both behaviors. Associations between trajectories of alcohol use and dating aggression were reduced substantially when common causes were controlled. Concurrent associations between the two behaviors were significant across nearly all grades but no evidence was found for prospective connections from prior alcohol use to subsequent dating aggression or vice versa. Findings suggest that prevention efforts should target common causes of alcohol use and dating aggression. PMID:23589667

Effectiveness of a social relations intervention program for aggressive and nonaggressive, rejected children.

Lochman, J E; Coie, J D; Underwood, M K; Terry, R

1993-12-01

A sample of 52 Black aggressive, rejected and nonaggressive, rejected children were randomly assigned to receive a social relations intervention or to be in a nonintervention control group. The school-based intervention for fourth-grade children focused on positive social skill training and cognitive-behavioral strategies to promote deliberate, nonimpulsive problem solving. At both the post-treatment and the 1-year follow-up assessments, the social relations intervention was found to be effective only with the aggressive, rejected children. Implications for the importance of assessing subtypes of rejected children are discussed.

The effects of environmental resource and security on aggressive behavior.

PubMed

Ng, Henry Kin Shing; Chow, Tak Sang

2017-05-01

Exposure to different environments has been reported to change aggressive behavior, but previous research did not consider the underlying elements that caused such an effect. Based on previous work on environmental perception, we examined the role of environmental resource and security in altering aggression level. In three experiments, participants were exposed to environments that varied in resource (High vs. Low) and security (High vs. Low) levels, after which aggression was measured. The environments were presented through visual priming (Experiments 1-2) and a first-person gameplay (Experiment 3). We observed a consistent resource-security interaction effect on aggression, operationalized as the level of noise blast (Experiment 1) and number of unpleasant pictures (Experiments 2-3) delivered to strangers by the participants. High resource levels associated with higher aggression in insecure conditions, but lower aggression in secure conditions. The findings suggest that the adaptive value of aggression varies under different environmental constraints. Implications are discussed in terms of the effects of adverse environments on aggression, and the nature's effects on social behavior. Aggr.

2014-01-01

Workplace aggression research has typically focused on groups in the health care industry considered to be high risk (e.g., nursing); however, aggression also occurs among other health care professional groups, such as those in allied health. This study aimed to investigate the antecedents and consequences of workplace aggression among allied health professionals. Allied health professionals working for an Australian health care organization were surveyed, with 134 (49%) responding. The largest group of allied health professionals surveyed were social workers (49%). Job demands, job control, and social support were linked to different types of aggression. Different sources of aggression were linked to various employee outcomes. The importance of considering stressors surrounding employee work conditions is highlighted.

2011-08-01

Prosocial behavior and aggression among children and adolescents are important indicators of social and interpersonal competence. The goal of this study was to investigate whether there are different prototypes among African American adolescents that can help explain prosocial and aggressive (relational and overt) behaviors. Also of interest was whether these profiles differed for boys and girls. The selection of independent variables (e.g., empathy, anger management, normative beliefs about aggression, and ethnic identity) was guided by an information processing model of aggression and prosocial behaviors. The sample consisted of 789 (57% female) African American adolescents between the ages of 11 and 14. Cluster analysis produced three profiles that were similar for boys and girls. These were labeled "well-adjusted," "poorly adjusted," and "low identity." A fourth profile was labeled "low empathy" for girls and "poor anger management" for boys. These four clusters significantly differentiated who engaged in prosocial behavior and relational and overt aggression. Findings suggest that prevention programs may consider targeting well-adjusted youth to serve as peer modes. Additionally, programs that promote empathy, anger management, ethnic identity, and normative beliefs against aggression may be useful for reducing aggression and increasing prosocial behavior among poorly adjusted youth.

Interactive contributions of self-regulation deficits and social motivation to psychopathology: Unraveling divergent pathways to aggressive behavior and depressive symptoms

PubMed Central

RUDOLPH, KAREN D.; TROOP-GORDON, WENDY; LLEWELLYN, NICOLE

2015-01-01

Poor self-regulation has been implicated as a significant risk factor for the development of multiple forms of psychopathology. This research examined the proposition that self-regulation deficits differentially predict aggressive behavior and depressive symptoms, depending on children’s social approach versus avoidance motivation. A prospective, multiple-informant approach was used to test this hypothesis in 419 children (M age = 8.92, SD = 0.36). Parents rated children’s inhibitory control. Children completed measures of social approach–avoidance motivation and depressive symptoms. Teachers rated children’s aggressive behavior. As anticipated, poor inhibitory control predicted aggressive behavior in boys with high but not low approach motivation and low but not high avoidance motivation, whereas poor inhibitory control predicted depressive symptoms in girls with high but not low avoidance motivation. This research supports several complementary theoretical models of psychopathology and provides insight into the differential contributions of poor self-regulation to maladaptive developmental outcomes. The findings suggest the need for targeted intervention programs that consider heterogeneity among children with self-regulatory deficits. PMID:23627953

[Sexual aggression against girls and adult women --definitions and epidemiology].

PubMed

Bitzer, J

2005-04-01

Various definitions of sexual aggression lead to different rates of incidence and prevalence. Crime statistics indicate the rate of declared judiciable acts (Hellfeld). Research definitions are broader with respect to behavior of the perpetrator, damage to the victim etc. (Dunkelfeld). Taking various data sources into account it emerges that 12-20% of women become victims of sexual aggression, which means that sexual aggression is ubiquitous in society reaching all ages and social classes, women being by far more often exposed than men.

2009-12-01

Suicide is one of the leading causes of death worldwide, mortality from suicide being approximately 2%. Attempted suicide appears to be a major risk factor for suicide completion. Anger, aggression and impulsivity are personality traits associated with suicide attempt. In this study we analysed a part of a previously reported sample in order to test anger, impulsivity and temperament/character scales as predictors of aggression and self-aggression in suicide attempters and to compare anger- and aggression-related traits between impulsive and premeditated suicide attempts as well as between violent and non-violent suicide methods. One-hundred-eleven consecutively admitted inpatients with a lifetime history of attempted suicide were assessed for anger (State-Trait Anger Expression Inventory, STAXI), aggression (Questionnaire for Measuring Factors of Aggression, FAF) and temperament/character (Temperament and Character Inventory, TCI). Higher aggression scores, as measured by FAF, were predicted by being male, meeting criteria for borderline personality disorder and having higher angry temperament scores as assessed by STAXI; low cooperativeness was also associated with aggression but not after controlling for STAXI scales. TCI dimensions associated with self-aggression were high harm avoidance, high impulsivity and low self-directedness; state anger, inwardly directed anger and inhibition of aggression were also predictors of self-aggression. In conclusion, impulsivity and harm avoidance have emerged as temperament dimensions independently associated with self-aggressive tendencies in personality. Such interactions could explain the correlation between temperament and suicidality but further research is needed. Anger and self-directedness appear to have some effects on suicide attempt.

Coyne, Sarah M; Archer, John; Eslea, Mike

2004-07-01

Numerous studies have shown that viewing violence in the media can influence an individual's subsequent aggression, but none have examined the effect of viewing indirect aggression. This study examines the immediate effect of viewing indirect and direct aggression on subsequent indirect aggression among 199 children ages 11 to 14 years. They were shown an indirect, direct, or no-aggression video and their subsequent indirect aggression was measured by negative evaluation of a confederate and responses to a vignette. Participants viewing indirect or direct aggression gave a more negative evaluation of and less money to a confederate than participants viewing no-aggression. Participants viewing indirect aggression gave less money to the confederate than those viewing direct aggression. Participants viewing indirect aggression gave more indirectly aggressive responses to an ambiguous situation and participants viewing direct aggression gave more directly aggressive responses. This study provides the first evidence that viewing indirect aggression in the media can have an immediate impact on subsequent aggression.

Aggression in autism spectrum disorder: presentation and treatment options

PubMed Central

Fitzpatrick, Sarah E; Srivorakiat, Laura; Wink, Logan K; Pedapati, Ernest V; Erickson, Craig A

2016-01-01

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent difficulties in social communication and social interaction, coupled with restricted, repetitive patterns of behavior or interest. Research indicates that aggression rates may be higher in individuals with ASD compared to those with other developmental disabilities. Aggression is associated with negative outcomes for children with ASD and their caregivers, including decreased quality of life, increased stress levels, and reduced availability of educational and social support. Therapeutic strategies including functional behavioral assessment, reinforcement strategies, and functional communication training may have a significant impact in reducing the frequency and intensity of aggressive behavior in individuals with ASD. Pharmacologic treatments, particularly the use of second-generation antipsychotics, may also be of some benefit in reducing aggression in individuals with ASD. With the ever-increasing rate of ASD diagnosis, development of effective therapeutic and pharmacologic methods for preventing and treating aggression are essential to improving outcomes in this disorder.

Thalamic modulation of aggression.

PubMed

Andy, O J; Giurintano, L; Giurintano, S; McDonald, T

1975-01-01

This experiment extends Pavlov's method of contrasts for 8 components of aggression were quantitatively evaluated in 11 freely moving adult cats. Aggression was elicited from the perifornix septohypothalamic areas by a series of progressively increasing and decreasing stimulation parameters. Three levels of thalamic stimulation (low, medium, and high) were combined with the perifornix stimulations. High level thalamic stimulation tended to facilitate the aggressive response elicited by low level perifornix stimulation. Thalamic lesions attenuated the aggression response, especially those elicited during high level perifornix stimulation. It was suggested that within the hypothalamic induced aggression circuitry the center median nucleus modulates the excitatory state of the system. The discussion concerns anatomic and physiologic pathways through which the center median nucleus may modulate the sensory, motor, and affective-autonomic subsystems into a well integrated aggressive state. These experimental findings are supported by the clinically established treatment of aggression by stereotaxic lesions placed in the center median nucleus.

The influence of violent and nonviolent computer games on implicit measures of aggressiveness.

PubMed

Bluemke, Matthias; Friedrich, Monika; Zumbach, Joerg

2010-01-01

We examined the causal relationship between playing violent video games and increases in aggressiveness by using implicit measures of aggressiveness, which have become important for accurately predicting impulsive behavioral tendencies. Ninety-six adults were randomly assigned to play one of three versions of a computer game that differed only with regard to game content (violent, peaceful, or abstract game), or to work on a reading task. In the games the environmental context, mouse gestures, and physiological arousal-as indicated by heart rate and skin conductance-were kept constant. In the violent game soldiers had to be shot, in the peaceful game sunflowers had to be watered, and the abstract game simply required clicking colored triangles. Five minutes of play did not alter trait aggressiveness, yet an Implicit Association Test detected a change in implicit aggressive self-concept. Playing a violent game produced a significant increase in implicit aggressive self-concept relative to playing a peaceful game. The well-controlled study closes a gap in the research on the causality of the link between violence exposure in computer games and aggressiveness with specific regard to implicit measures. We discuss the significance of importing recent social-cognitive theory into aggression research and stress the need for further development of aggression-related implicit measures.

Alcohol-related aggression during the college years: theories, risk factors and policy implications.

PubMed

Giancola, Peter R

2002-03-01

The purpose of this article is to present an overview of the research literature on alcohol-related aggression with a focus on college students. Data from both survey studies and experimental laboratory investigations conducted on college students are reviewed. Various methodological approaches to studying the alcohol-aggression relation, and their associated limitations, are then presented and discussed. The literature indicates that alcohol consumption facilitates aggressive behavior and increases the risk of being the victim of a violent act, particularly in heavy drinkers. Results from these studies are then placed into a context by reviewing 12 influential theories of aggression and alcohol-related aggression. On the basis of these theories and empirical data, a preliminary risk profile is presented to help identify which factors are likely to be important in predicting who will and who will not become aggressive after drinking alcohol. Although much research is still needed to elucidate the intricate causes of alcohol-related aggression, current prevention efforts might focus on modifying key risk factors such as poor cognitive functioning and inaccurate expectations about the effects of alcohol. Other prevention efforts directed specifically at college students might focus on helping them to identify risky situations that might facilitate the expression of intoxicated aggression.

Parental reactions to parent- and sibling-directed aggression within a domestic violence context.

PubMed

Desir, Michelle P; Karatekin, Canan

2018-02-01

Parent- and sibling-directed aggression by minor children are two forms of family violence that often co-occur and have strong relations to prior exposure to domestic violence, yet are often overlooked in intervention efforts. In addition, current research does not examine these forms of family violence in tandem, and there is very limited research with samples exposed to domestic violence. To better understand how these forms of aggression operate within a domestic violence context, we interviewed 44 women residing in a domestic violence shelter with at least one child over 3.5 years of age who was aggressive toward them and/or siblings. Caregivers reported on their emotional reactions to children's parent-directed aggression and the types of and effectiveness of help they sought for parent- and/or sibling-directed aggression. In line with previous literature, caregivers endorsed a complex mix of emotional reactions to their children's parent-directed aggression, including anger, sadness, guilt, forgiveness, and worthlessness. In contrast to other studies, most caregivers (89%) had sought help for children's parent- and/or sibling-directed aggression and found it effective. Findings contribute to the literature on parent- and sibling-directed aggression and provide implications for how to effectively intervene.

2013-01-01

Rationale Preclinical experimental models of pathological aggressive behavior are a sorely understudied and difficult research area. Objectives How valid, reliable, productive and informative are the most frequently used animal models of excessive aggressive behavior? Methods The rationale, key methodological features, supporting data and arguments as well as their disadvantages and limitations of the most frequently used animal models for excessive aggressive behavior are summarized and their validity and reliability are evaluated. Results Excessive aggressive behavior is validly and reliably seen in (1) a proportion of feral-derived rats and selectively bred mice, (2) rats with compromised adrenal function resulting in a hypoglucocorticoid state, (3) a significant minority of mice, rats and monkeys after consumption of a moderate dose of alcohol, and (4) resident animals of various species after social instigation. Limitations of these procedures include restrictive animal research regulations, the requirement of expertise in surgical, pharmacological and behavioral techniques, and the behaviorally impoverished mouse strains that are used in molecular genetics research. Promising recent initiatives for novel experimental models include aggressive behaviors that are evoked by optogenetic stimulation and induced by the manipulation of early social experiences such as isolation rearing or social stress. Conclusions One of the most significant challenges for animal models of excessive, potentially abnormal aggressive behavior is the characterization of distinctive neurobiological mechanisms that differ from those governing species-typical aggressive behavior. Identifying novel targets for effective intervention requires increased understanding of the distinctive molecular, cellular and circuit mechanisms for each type of abnormal aggressive behavior.

This chapter describes the state of knowledge on the development of physical aggression from early childhood to adulthood, the long term outcomes of chronic physical aggression during childhood and the risk factors for chronic physical aggression. Unraveling the development of physical aggression is important to understand when and why humans start using physical aggression, to understand why some humans suffer from chronic physical aggression and to understand how to prevent the development of this disorder which causes much distress to the aggressors and their victims. The study of the developmental origins of aggression also sheds light on the reasons why situational prevention of aggression is important at all ages and in all cultures.

2015-01-01

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. PMID:21186935

Objective Stimulant treatment improves impulse control among children with attention-deficit/hyperactivity disorder (ADHD). Decreased aggression often accompanies stimulant pharmacotherapy, suggesting that impulsiveness is integral to their aggressive behavior. However, children with high callous-unemotional (CU) traits and proactive aggression may benefit less from ADHD pharmacotherapy because their aggressive behavior seems more purposeful and deliberate. This study’s objective was to determine if pretreatment CU traits and proactive aggression affect treatment outcomes among aggressive children with ADHD receiving stimulant monotherapy. Method We implemented a stimulant optimization protocol with 160 6- to 13-year-olds (mean [SD] age of 9.31 [2.02] years; 78.75% males) with ADHD, oppositional defiant or conduct disorder, and significant aggressive behavior. Family-focused behavioral intervention was provided concurrently. Primary outcome was the Retrospective Modified Overt Aggression Scale. The Antisocial Process Screening Device and the Aggression Scale, also completed by parents, measured CU traits and proactive aggression, respectively. Analyses examined moderating effects of CU traits and proactive aggression on outcomes. Results 82 children (51%) experienced remission of aggressive behavior. Neither CU traits nor proactive aggression predicted remission (CU traits: odds ratio=0.94, 95% CI=0.80–1.11; proactive aggression, odds ratio=1.05, 95% CI=0.86–1.29). Children whose overall aggression remitted showed decreases in CU traits (effect size=−0.379, 95% CI=−0.60 to −0.16) and proactive aggression (effect size=−0.463, 95% CI=−0.69 to −0.23). Conclusions Findings suggest that pretreatment CU traits and proactive aggression do not forecast worse outcomes for aggressive children with ADHD receiving optimized stimulant pharmacotherapy. With such treatment, CU traits and proactive aggression may decline alongside other behavioral improvements

Little attention has been given to whether adolescents' beliefs about anonymity and their normative beliefs about cyber aggression jointly increase their perpetration of cyber aggression. To this end, the present longitudinal study examined the moderating influence of these variables on the relationships among adolescents' attitudes toward the permanency of digital content, confidence with not getting caught, and anonymous cyber aggression (ACA) assessed 1 year later (Time 2). These associations were examined among 274 7th and 8th graders and through five technologies, including social networking sites (SNS), e-mail, instant messenger (IM), mobile phones, and chatrooms. Findings indicated that increases in Time 2 ACA and attitudes toward the permanency of digital content were more strongly related when adolescents reported greater confidence with not getting caught and higher normative beliefs concerning cyber aggression through SNS and mobile phones. In addition, higher levels of attitudes toward the permanency of digital content, confidence with not getting caught, beliefs about anonymity, and normative beliefs regarding cyber aggression were related to greater Time 2 ACA through e-mail, IM, and chatrooms. All findings are discussed in the context of adolescents' positive attitudes toward ACA, and an appeal for additional research is made to understand more about anonymity in cyberspace.

The distinction between aggressive and passive victims of school bullying is well documented. Aggressive victims exhibit restlessness and hot-temperedness, are easily provoked, and take revenge when irritated, whereas passive victims are quiet and timid when attacked or insulted and withdraw rather than retaliate. To date, there has been no evidence-based evaluative study examining interventions designed specifically to reduce aggressive victimization, and neither has there been an inclusive assessment screening of high-risk aggressive victims prior to intervention. This study addressed these research gaps by employing multi-stage assessment procedures and a mixed-mode methodology in a one-year longitudinal design. Data were collected from student self-reports, parent and teacher rating scales, and individual structured interviews with students, parents and teachers. A total of 269 potential high-risk aggressive victims were identified from among 5,089 schoolchildren, 68 of whom were screened out and randomly assigned to 10 treatment groups, with 39 completing a one-year follow-up study. Multivariate analysis of variance identified significant improvements in physical and verbal victimization (F(2,47, 93.99) = 10.73, p < 0.01), verbal victimization (F(2.74, 104.14) = 12.80, p < 0.01) and social exclusion scores at the three follow-up assessments compared to the pre-treatment scores, and the qualitative results were consistent, showing participants' cognition, emotion, and behavior to have been positively reconstructed by the group intervention. The consistent quantitative and qualitative results confirm that the cognitive-behavioral group therapy program reported herein is effective in reducing aggressive victims' anxious and depressed emotions and reactive cognition. © 2012 The Author.

To develop new strategies for preventing violence in high-risk licensed premises, we identify behavioural indicators of apparent motives for aggression in these settings and outline the implications of different motivations for prevention. The four types of motives for aggressive or coercive acts defined by the theory of coercive actions framed the research: gaining compliance, expressing grievances/restoring justice, attaining a favourable social identity and pursuing fun/excitement. Incidents of aggression from the Safer Bars evaluation research were analysed to identify behavioural indicators of each motivation. Compliance-motivated aggression typically takes the form of unwanted social overtures, third party intervention to stop conflicts or staff rule enforcement. Prevention strategies include keeping the aggressor's focus on compliance to avoid provoking grievance and identity motives that are likely to escalate aggression. Grievance motives are typically elicited by perceived wrongdoing and therefore prevention should focus on eliminating sources of grievances and adopting policies/practices to resolve grievances peacefully. Social identity motives are endemic to many drinking establishments especially among male patrons and staff. Prevention involves reducing identity cues in the environment, hiring staff who do not have identity concerns, and training staff to avoid provoking identity concerns. Aggression motivated by fun/excitement often involves low-level aggression where escalation can be prevented by avoiding grievances and attacks on identity. Knowledge of behavioural indicators of motives can be used to enhance staff hiring and training practices, reduce environmental triggers for aggression, and develop policies to reduce motivation for aggression. © 2011 Australasian Professional Society on Alcohol and other Drugs.

The aim of this study was to identify the existence of combinations of aggression components (Anger, Hostility, Physical Aggression and Verbal Aggression) that result in different profiles of aggressive behavior in children, as well as to test the differences between these profiles in scores of perfectionism, school refusal and affect. It is interesting to analyze these variables given: (a) their clinical relevance due to their close relationship with the overall psychopathology; and (b) the need for further evidence regarding how they are associated with aggressive behavior. The sample consisted of 1202 Spanish primary education students between the ages of 8 and 12. Three aggressive behavior profiles for children were identified using Latent Class Analysis (LCA): High Aggression (Z scores between 0.69 and 0.7), Moderate Aggression (Z scores between −0.39 and −0.47) and Low Aggression (Z scores between −1.36 and −1.58). These profiles were found for 49.08%, 38.46% and 12.48% of the sample, respectively. High Aggression scored significantly higher than Moderate Aggression and Low Aggression on Socially Prescribed Perfectionism (SPP), Self-Oriented Perfectionism (SOP), the first three factors of school refusal (i.e., FI. Negative Affective, FII. Social Aversion and/or Evaluation, FIII. To Pursue Attention), and Negative Affect (NA). In addition, Moderate Aggression also reported significantly higher scores than Low Aggression for the three first factors of school refusal and NA. Conversely, Low Aggression had significantly higher mean scores than High Aggression and Moderate Aggression on Positive Affect (PA). Results demonstrate that High Aggression was the most maladaptive profile having a high risk of psychological vulnerability. Aggression prevention programs should be sure to include strategies to overcome psychological problems that characterize children manifesting high levels of aggressive behavior. PMID:29441002

Aggression in residential youth care institutions is a frequent problem. The present short-term longitudinal study examined individual and institutional predictors of aggression in a group of 198 adolescents placed in open, semi-secure and secure residential institutions from the perspective of the importation and deprivation model. A total of 198 adolescents in residential youth care filled in questionnaires regarding group climate and aggression with a 3 month interval. Hierarchical multiple regression analyses were performed to test the degree to which individual and contextual factors predict aggression. Very limited support was found for the effect of contextual factors; only repression showed a trend, predicting direct aggression, while gender composition of the living groups yielded a small effect. Girls placed in same-gender groups showed lower levels of indirect (relational) aggression compared to adolescents placed in mixed-gender or boys-only groups, even when controlled for gender and initial levels of aggression. Type of institution (i.e., level of security) did not predict differences in aggression. In particular individual characteristics of the adolescents were associated with later aggression, including initial levels of aggression, showing substantial 3 months stability, age and gender of the adolescents. These findings are in line with research showing that aggression is relatively stable. Very limited support for environmental effects was found.

Life Course Associations between Victimization and Aggression: Distinctive and Cumulative Contributions

The connections between early maltreatment and later aggression are well established in the literature, however gaps remain in our understanding of developmental processes. This study investigates the cascading life course linkages between victimization experiences from childhood through early adulthood and later aggressive behavior. The diverse, at-risk sample is of particular importance to child and adolescent specialists, as it represents highly vulnerable youth accessible through conventional school settings. In addition to direct pathways from proximal life periods, path analysis revealed significant indirect mediated pathways through which earlier life victimization contributes to aggressive behaviors in later life periods as well as revictimization. Multivariate regressions support theorized cumulative effects of multi-form victimization as well as distinct contributions of victimization domains (emotional, witnessing, physical, property, and sexual) in explaining aggressive behavior. Consistent with theorizing about the developmental impact of early maltreatment, results bolster the importance of interrupting pathways from victimization to revictimization and later aggression. Findings are evaluated in light of implications for early identification and prevention programming. PMID:26190900

In the different psychiatric disorders the aggression often leads to uncontrolled events, taking aspects of impulsiveness and irrationality. Our research proposes the assessment of socio-demographic and clinical characteristics of patients with a psychiatric disorder, who presented an aggressive event. The observational study was conducted on a sample of 50 patients (34 men and 16 women), hospitalized following the manifestation of an aggressive event. For each patient was provided an assessment of socio-demographic and clinical variables and a psychometric investigation through: the OAS, for the analysis of aggressive episodes; the BDHI, for the hostile behavior and attitudes; the BIS-11, for the impulsiveness and the BPRS for the psychopathological aspects. Among the socio-demographic features investigated, the highest correlation with aggressive behavior was related to the concomitant substance abuse, type of admission to psychiatric hospital and the male gender. The OAS has shown a greater propensity to directed-aggression in males with schizophrenia, and self-directed in females with major depression. The BPRS has shown a positive correlation between hetero-directed aggressive behavior and positive symptomatology, and between the self-directed and depression, risk of suicide, feelings of guilt and somatic concerns. The BDHI has indicated greater suspicion in women's group. The hypothesis that aggression is otherwise related to specific socio-demographic and clinical characteristics was confirmed by our study. The data suggest that early identification and assessment of potential risk factors involved in the genesis of aggressive episodes would allow the clinician to implement a better strategy for prevention and intervention.

Sibling aggression is a common form of intra-familial aggression, yet has been largely neglected by research. Using an inclusive measure of sibling aggression, this study investigated, firstly, prevalence of sibling aggression and associations with family and household characteristics, and secondly, the relationship between sibling aggression and peer bullying. Participants were 4,237 adolescents from Wave 1 of Understanding Society. Four types of sibling aggression were measured: physical, verbal, stealing and teasing, and combined into composite measures of victimization and perpetration. Regression analysis identified associations with demographic characteristics, family and sibling composition, parent-child relationships and socioeconomic status and explored the link between sibling aggression and involvement in peer bullying. Using a broad definition, sibling aggression was found to be widespread, with 46% of all participants being victimized and 36% perpetrating aggression. Household and family characteristics, including a large family size, male siblings, and financial difficulties were associated with greater rates of sibling aggression. Parenting behavior showed the strongest relationship: harsh parenting increased the risk of sibling aggression while positive parenting protected against it. Sibling aggression was also homotypically related to involvement in peer bullying. Victimization by siblings significantly increased the odds of being a victim of peer bullying, and perpetrators of sibling aggression were more likely to be both peer bullies and bully-victims. Considering the adverse effects of sibling aggression on physical and mental health, the study provides pointers for efforts to reduce the risk of sibling aggression. Furthermore, the link with peer bullying suggests that school anti-bullying efforts should also take account of children's sibling relationships. Aggr.

Staff gender ratio and aggression in a forensic psychiatric hospital.

Gender balance in acute psychiatric inpatient units remains a contentious issue. In terms of maintaining staff and patient safety, 'balance' is often considered by ensuring there are 'sufficient' male nurses present on each shift. In an ongoing programme of research into aggression, the authors investigated reported incidents of patient aggression and examined the gender ratio on each shift over a 6-month period. Contrary to the popular notion that a particular gender ratio might have some relationship with the likelihood of aggressive incidents, there was no statistically significant difference in the proportion of male staff working on the shifts when there was an aggressive incident compared with the shifts when there was no aggressive incident. Further, when an incident did occur, the severity of the incident bore no relationship with the proportion of male staff working on the shift. Nor did the gender of the shift leader have an impact on the decision to seclude the patient or the likelihood of completing an incident form following an aggressive incident. Staff confidence in managing aggression may be influenced by the presence of male staff. Further, aspects of prevention and management may be influenced by staff gender. However, results suggest there is no evidence that the frequency or severity of aggression is influenced by staff gender ratio.

The General Aggression Model.

PubMed

Allen, Johnie J; Anderson, Craig A; Bushman, Brad J

2018-02-01

The General Aggression Model (GAM) is a comprehensive, integrative, framework for understanding aggression. It considers the role of social, cognitive, personality, developmental, and biological factors on aggression. Proximate processes of GAM detail how person and situation factors influence cognitions, feelings, and arousal, which in turn affect appraisal and decision processes, which in turn influence aggressive or nonaggressive behavioral outcomes. Each cycle of the proximate processes serves as a learning trial that affects the development and accessibility of aggressive knowledge structures. Distal processes of GAM detail how biological and persistent environmental factors can influence personality through changes in knowledge structures. GAM has been applied to understand aggression in many contexts including media violence effects, domestic violence, intergroup violence, temperature effects, pain effects, and the effects of global climate change.

Anger is an empirically established precipitant to aggressive responding toward intimate partners. The current investigation examined the effects of anger, as experienced by both partners, as well as gender and previous aggression, on in vivo intimate partner aggression using a prospective daily diary methodology. Participants (N = 118 couples) individually provided 56 consecutive, daily reports of affective experience and partner aggression. Multilevel models were estimated using the Actor Partner Interdependence Model framework to analyze the daily associations between anger and partner aggression perpetration among male and female participants as moderated by aggression history. Results revealed that both Actor and Partner anger were generally associated with subsequently reported daily conflict. Further, increases in daily Partner anger were associated with corresponding increases in partner aggression among females who reported high anger and males, regardless of their own anger experience. Increases in Actor anger were associated with increases in daily partner aggression only among previously aggressive females. Previously aggressive males and females consistently reported greater perpetration than their nonaggressive counterparts on days of high Actor anger experience. Results emphasize the importance of both Actor and Partner factors in partner aggression and suggest that female anger may be a stronger predictor of both female-to-male and male-to-female partner aggression than male anger, when measured at the daily level.

Stimulant treatment improves impulse control among children with attention-deficit/hyperactivity disorder (ADHD). Decreased aggression often accompanies stimulant pharmacotherapy, suggesting that impulsiveness is integral to aggressive behavior in these children. However, children with high callous-unemotional (CU) traits and proactive aggression may benefit less from ADHD pharmacotherapy, because their aggressive behavior seems more purposeful and deliberate. This study's objective was to determine whether pretreatment CU traits and proactive aggression affect treatment outcomes among aggressive children with ADHD receiving stimulant monotherapy. We implemented a stimulant optimization protocol with 160 children 6 to 13 years of age (mean [SD] age of 9.31 [2.02] years; 78.75% male) with ADHD, oppositional defiant or conduct disorder, and significant aggressive behavior. Family-focused behavioral intervention was provided concurrently. The primary outcome was the Retrospective Modified Overt Aggression Scale. The Antisocial Process Screening Device and the Aggression Scale, also completed by parents, measured CU traits and proactive aggression, respectively. Analyses examined moderating effects of CU traits and proactive aggression on outcomes. In all, 82 children (51%) experienced remission of aggressive behavior. Neither CU traits nor proactive aggression predicted remission (CU traits: odds ratio [OR] = 0.94, 95% CI = 0.80-1.11; proactive aggression, OR = 1.05, 95% CI = 0.86-1.29). Children whose overall aggression remitted showed decreases in CU traits (effect size = -0.379, 95% CI = -0.60 to -0.16) and proactive aggression (effect size = -0.463, 95% CI = -0.69 to -0.23). Findings suggest that pretreatment CU traits and proactive aggression do not forecast worse outcomes for aggressive children with ADHD receiving optimized stimulant pharmacotherapy. With such treatment, CU traits and proactive aggression may decline alongside other behavioral improvements

Does worry moderate the relation between aggression and depression in adolescent girls?

Aggressive girls, more so than aggressive boys, are at an increased risk for depression. Despite disconcerting outcomes, few researchers have examined factors that may attenuate or exacerbate the relation between aggression and depression. Competing hypotheses for explaining the role of worry in the relation between aggressive behaviour and depressive symptoms, commonly co-occurring problems in girls, have been proposed. In the present study, we examined worry as a possible moderator in the relation between girls nominated as aggressive by their peers and self-reported depressive symptoms in a sample of 226 girls aged 13 (M = 12.92, SD = 1.28) at Time 1. We found that worry exacerbated the risk of depressive symptoms concurrently and one year later for physically aggressive girls, but not relationally aggressive girls. These results suggest that worry plays an important role in the prediction of depression for aggressive girls, which varies by the form aggression takes.
